 ## Why LiveAgent?
 
-LiveAgent is a **local-first** AI agent desktop client. It deeply integrates large language model reasoning with local system tools, so the AI can genuinely operate your file system, run commands, and manage scheduled tasks — while the Gateway enables remote access and collaboration.
+LiveAgent is a **self-hosted** AI agent you run yourself. It deeply integrates large language model reasoning with real system tools, so the AI can genuinely operate your file system, run commands, and manage scheduled tasks — and you reach it from a desktop app or a browser, both talking to the same backend.
 
 - **An agent that actually gets things done** — beyond chat: read and write files, make precise edits, run Bash, and supervise long-running processes
 - **A fully open ecosystem** — bridge any external tool via the MCP protocol, and load Skills packages on demand
-- **Both local and remote** — the desktop app works fully standalone; deploy the Gateway and control it from any browser
+- **Your keys stay on your backend** — the backend is the only thing that holds credentials, and you decide where it runs: your laptop, your home server, or your own VPS

+### Need Remote Access? (Legacy Gateway)
 
-The desktop app works out of the box and depends on no server. Deploy the Gateway only if you want to **control your local agent from a browser**.

+> v2.0 会断。已经部署的用户请先读 [v2.0 迁移指南](#v20-迁移指南--v20-migration-guide)。
+
+In v2.0 there is no Gateway: you deploy the **backend** where you want it, and the desktop app or a browser points straight at it. If the backend sits behind NAT and you are not, that is a networking problem with networking answers — [Tailscale](https://tailscale.com/), [frp](https://github.com/fatedier/frp), or [Cloudflare Tunnel](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/) — not something the app punches through for you.
+
+The instructions below are the v1 Gateway path, kept for users who already run it.
 
 **Note: when deployed behind an Nginx reverse proxy, set the Gateway address on the Settings → Remote page to the HTTPS URL and use port 443.**

+The desktop shell is a shell: it renders the frontend and adds native niceties
+(tray, notifications, file dialogs). It is not a second implementation — point
+the same frontend at a remote backend URL and everything works identically.

+## v2.0 迁移指南 / v2.0 Migration Guide
+
+**v2.0 会改掉远程访问的整个架构。已经部署 `ghcr.io/stack-cairn/liveagent-gateway`
+的用户一定会断 —— 这是无法避免的破坏性变更,不是 bug。**
+
+### 为什么会断
+
+旧模型:桌面端**主动拨出**连到 Gateway,浏览器再连 Gateway,Gateway 在中间转发。
+新模型:后端(Rust + Node)自己就是服务端,**前端直接连后端**。
+
+两边都在等对方来连,技术上对不上,没有兼容层可写。
+
+### 你的选择
+
+| 情况 | 怎么办 |
+|---|---|
+| 现在跑得好好的,不想动 | **什么都不用做。** 旧镜像 tag 冻结保留、可以继续拉;旧桌面端配旧网关继续可用 |
+| 想升到 v2.0 | 按下面的步骤迁移 |
+
+旧镜像会一直留在 registry 里,但**不再收到更新**(包括安全修复)。
+
+### 迁移步骤
+
+1. **把旧版本钉死,不要用 `:latest`。** 升级前先确认旧部署用的是具体 tag:
+
+   ```bash
+   docker pull ghcr.io/stack-cairn/liveagent-gateway:v1  # 冻结的旧 tag
+   ```
+
+2. **备份 Gateway 数据卷。** 里面有 Agent token 和数据库:
+
+   ```bash
+   docker run --rm -v liveagent-gateway-data:/data -v "$PWD":/backup \
+     alpine tar czf /backup/liveagent-gateway-backup.tar.gz -C /data .
+   ```
+
+3. **在要远程访问的那台机器上部署 v2.0 后端**(替代 Gateway 容器)。
+   它同时提供 HTTP API、WebSocket 和前端静态资源,一个端口。
+
+4. **前端只需要两样东西:base URL + 密码。**
+   「连到哪个 Gateway」「Agent ID」「自动重连」「心跳间隔」这些设置项在 v2.0
+   不存在了 —— 本地和远程的唯一差别就是那个 base URL:
+
+   ```ts
+   const backend = createBackendClient({ baseUrl, password });
+   ```
+
+   - 桌面版:壳自动注入密码,跳过登录页,双击即用
+   - 浏览器:访问后端地址,走登录页输密码
+
+5. **旧 Agent token 不迁移。** v2.0 用密码直接当 Bearer token,旧的 Agent token
+   体系没有对应物。部署后端时重新设一个密码即可。
+
+6. **确认无误后再删旧容器:**
+
+   ```bash
+   docker rm -f liveagent-gateway
+   ```
+
+### 新桌面端连旧网关会怎样
+
+不会静默失败,但目前的提示是**调用时**给的,不是配置时给的:前端仍残留的
+`gateway_*` 调用点会被本地拦下并抛出
+
+> v2 不再需要 Gateway:桌面端不再外拨连接它,改为前端直连后端(本机或远程)。
+> 迁移步骤见 README 的 v2 迁移指南。
+
+「在设置页检测到旧网关地址就直接提示」还没做。

+<summary><b>Where do my API keys live?</b></summary>
 
-No. Keys are stored locally on the desktop side only. The Gateway is a pure protocol relay — it never accesses the file system and never stores any credentials.
+Only on the backend — and you decide where the backend runs. The frontend never sees a key: it sends commands, the backend calls the model. If you run the backend on your own laptop the keys never leave the machine; if you deploy it to your own server, they live there and nowhere else. There is no service of ours in the path.

-No. The desktop client works standalone with all local capabilities; deploy the Gateway only when you need browser-based remote access to your local agent.
+Not for local use — the desktop app ships the backend inside it and works out of the box. Deploy the backend separately when you want to reach the same agent from a browser, from another machine, or keep it running while your laptop is closed.

+只在后端 —— 而后端跑在哪里由你决定。前端从头到尾看不到密钥:它只发命令,由后端去调模型。后端跑在自己笔记本上,密钥就不出这台机器;部署到自己的服务器上,密钥就只在那台服务器上。链路里没有任何我们的服务。

-// The conversation stream store is the authoritative relay state for chat:

-//
-// Invariants (all enforced under the single store mutex):
-//  1. Seq is conversation-scoped and monotonic; runs do not own seq.
-//  2. run_finished is emitted exactly once per run — the first terminal
-//     signal wins, later duplicates are swallowed via the finished-run ring.
-//  3. Run handoff is supersession: run_started(B) while A is running
-//     atomically synthesizes run_finished(A) first.
-//  4. Activity events are composed inside the locked transition that changed
-//     them, so they always carry the run id.
-//  5. Subscriber sends happen under the mutex (non-blocking); an overflowing
-//     subscriber is closed and resumes by re-subscribing with after_seq.

-# agent-gateway tests
-
-All project-level gateway tests live under `crates/agent-gateway/test` and are split by boundary:
-
-| Directory | Coverage |
-| --- | --- |
-| `auth/` | HTTP bearer parsing and WebSocket token auth behavior |
-| `http/` | Gateway HTTP route auth, `/api/status`, and SPA fallback |
-| `upload/` | `/api/files/import` validation, multipart parsing, and agent forwarding |
-| `websocket/` | WebSocket auth, request forwarding, chat streaming, and cancellation-facing events |
-| `webui/` | Browser-side WebUI helpers, auth, upload normalization, history state, live stream state, and WebSocket client behavior |
-| `../web/test/` | WebUI source-adjacent module tests for chat transcript, history scope, and live conversation commit helpers |
-| `helpers/` | Shared Node test module loader for WebUI TypeScript modules |
-
-Run Go-side tests from `crates/agent-gateway`:
-
-```sh
-go test ./...
-```
-
-Run WebUI Node tests from `crates/agent-gateway`:
-
-```sh
-node --test test/webui/*.test.mjs web/test/*.test.mjs
-```
-
-Run the WebUI type/build gate separately from `crates/agent-gateway/web`:
-
-```sh
-pnpm build
-```

-// Lazy history-window bookkeeping for opening/refreshing a conversation.
-//
-// The web end renders a conversation from tail windows of the persisted
-// history (`history.get` with `max_messages`). Instead of hydrating the full
-// conversation at idle — which makes open cost and per-turn quiet-refresh
-// cost proportional to the conversation's lifetime size — the app tracks,
-// per conversation, the oldest persisted message it has loaded:
-//
-//   oldestOffset — number of persisted messages ABOVE the loaded window
-//                  (0 means the window starts at the very first message)
-//   lastTotal    — the freshest total_message_count this client observed:
-//                  the latest applied fetch, bumped forward by history-upsert
-//                  summary counts (noteHistoryWindowTotal)
-//
-// Requests are EDGE-ANCHORED: a quiet refresh asks for
-// `lastTotal - oldestOffset` messages, so the window always spans everything
-// persisted after the established edge (covering every exchange streamed
-// this session — alignEnrich requires the window to reach the live turns)
-// while messages above the edge stay unfetched until the user pages up.
-// "Load earlier" grows the request beyond the edge by a page.
-//
-// Because the tail window is anchored to the END of the conversation,
-// concurrent appends between "compute request size" and "serve response"
-// SLIP the returned window's top edge below the established one. Applying a
-// slipped window could hand alignEnrich a window that no longer covers the
-// rendered region's coverage counts (its count-coincidence full-window branch
-// could then rebuild the region without the rows above the slipped edge), so
-// slipped responses are never applied: the caller retries once with the
-// corrected size from the response's authoritative total, and skips the
-// cycle when the edge slipped again (the app's quiet-refresh loops converge
-// on a later pass).
-//
-// The slip retry is the SAFETY NET, not the steady state: the desktop
-// persists a run's messages before it reports completion, and the history
-// upsert it publishes at that flush carries the new total. Folding that
-// total into `lastTotal` (noteHistoryWindowTotal) before the busy→idle
-// refresh plans its span makes the common post-turn refresh a single

-// The sidebar state store: one external store per app instance holding the
-// workspace/conversation sidebar domain — conversation list, workdir
-// summaries, running set, and per-row mutations. Consumed from React through
-// useSidebarSelector so a store commit re-renders selector subscribers only,
-// never the page-level components. Byte-mirrored between agent-gui and
-// agent-gateway/web; everything platform-specific arrives via SidebarBackend.
-//
-// Consistency policy (stale-while-revalidate):
-// - a fetch failure never clears the visible list;
-// - a scope switch first shows the cached slice of the new scope (syncing),
-//   the skeleton appears only when nothing is cached (loading);
-// - authoritative pages drop server-absent rows except pending drafts,
-//   in-flight mutations, and adapter-protected ids — reconnects therefore
-//   remove conversations deleted elsewhere instead of resurrecting them.

-// Scroll-follow core for bottom-pinned live views: the chat transcript
-// viewport and the thinking-block <pre> both run on this reducer via
-// useScrollFollow.
-//
-// This replaces the 2026-07 scrollFollowPolicy after four rounds of
-// device-specific patches. Instead of refining the "was that scroll the user
-// or us?" classification, the architecture removes the question:
-//
-// - DETACH happens only on explicit user input (wheel-up, touch drag, history
-//   keys) or on away-movement during a real pointer drag — scrollbar thumb
-//   drags and selection auto-scroll are the only user paths away from the
-//   bottom that arrive solely as scroll events. Windows WebView2's compositor
-//   keeps emitting scroll frames from a stale wheel smooth-scroll trajectory
-//   after a programmatic pin (the abort lands with the next main-thread
-//   commit); those frames carry no input and no drag, so they can never
-//   detach.
-// - ATTACH is position-driven and intent-gated: landing at the physical clamp
-//   attaches while following (our own pin write echoing back) or inside an
-//   active gesture latch; a gesture-latched downward arrival inside the
-//   reattach zone attaches; a pointer released inside the zone after downward
-//   movement attaches. Content shrinking under a detached reader (a reply
-//   settling out of the row list, a collapsing block) also clamps scrollTop
-//   to the bottom with no input — that arrival carries no latch, so it can
-//   never re-engage follow and the next growth cannot yank the reader down.
-//   The gesture latch is the only timing heuristic left and it gates attach
-//   only — a false positive re-pins, it can never tear follow down.
-// - While following, a scroll event that leaves a gap open is corrected by
-//   re-pinning rather than classified.
-// - ResizeObserver deliveries (contentGrowth) never change follow state; they
-//   pin while following and keep direction bookkeeping honest otherwise.
-//   Content growth widens the gap with no user input — treating it as
-//   "scrolling away" tore down freshly re-engaged follows on stream flushes.
-//
-// Pure and DOM-free: useScrollFollow gathers the per-event facts and applies
-// `pin` effects. Every behavior is unit-tested in
-// test/chat/scroll-follow-core.test.mjs.
-
-// Hard "at bottom" tolerance. Fractional devicePixelRatio displays (Windows
-// 125%/150% scaling, zoomed webviews) clamp scrollTop 1-3px short of

-# agent-gui tests
-
-All new project-level tests live under `crates/agent-gui/test` and are split by feature area:
-
-| Directory | Coverage |
-| --- | --- |
-| `settings/` | Settings normalization, provider routing, hooks, cron, MCP, remote config |
-| `chat/` | Uploaded files, UI message rounds, seed tool recovery, conversation segments |
-| `providers/` | Proxy URL validation, provider payload hooks, caching, storage metadata |
-| `tools/` | Workspace-relative path validation and custom system tool registration |
-| `i18n/` | Locale normalization and translation key parity |
-| `backend/` | Cargo smoke test that runs the existing Tauri backend unit suite |
-
-Run everything from `crates/agent-gui`:
-
-```sh
-pnpm test
-```
-
-Run only the faster frontend/node tests:
-
-```sh
-pnpm test:frontend
-```
-
-Run only the backend smoke wrapper:
-
-```sh
-pnpm test:backend
-```

+//!
+//! 挂子路径(`/t/<id>/`)时,dev server 吐的 `<script src="/assets/main.js">`
+//! 会打到隧道之外,于是必须重写它发出的每一个 URL——HTML 属性、CSS `url()`、
+//! 以及运行时的 fetch/XHR/WebSocket(Go 版 `tunnel_rewrite.go` 约 1000 行)。

+//! 独立端口下这个绝对路径本来就是对的。**重写代码为 0 行**——不是写得更好,
+//! 是整类问题不存在。这就是「重新设计数据结构让特殊情况消失」。
+//!
+//! ## 认证
+//!
+//! 浏览器标签页发不了 `Authorization` 头,所以后端密码在这里用不上。改用:
+//!
+//! ```text
+//! 首访 http://host:port/?t=<token>  →  校验 → Set-Cookie → 302 到干净路径
+//! 后续 http://host:port/...          →  带 cookie 直接放行
+//! ```
+//!
+//! 这与旧架构靠「不可猜的 slug」做能力凭证是同一强度,但更好一点:端口可以被
+//! 扫到,token 不能。token 常量时间比较,与主 API 的密码校验同一标准。

+//! 本机隧道:把工作机上的 dev server 暴露成一个可访问的 HTTP 端口。
+//!
+//! ## 与旧实现的区别
+//!
+//! 旧实现里隧道是「桌面端 → 公网 Gateway」的注册协议:端口注册到 Gateway,
+//! Gateway 开 `/t/{slug}` 公开反代,把每个 HTTP 请求/WS 帧拆成 protobuf 帧
+//! 跨中继来回搬,再重写 HTML 属性、CSS `url()`、注入 shim、改 CSP
+//! (`tunnel_rewrite.go`,约 1000 行)才能让子路径下的页面正常工作。
+//!
+//! 新架构里后端**就在**那台工作机上,且自己就是网络入口。于是:
+//!
+//! | 旧 | 新 |
+//! |---|---|
+//! | slug 注册协议 | 没有。id 本地生成,不需要跟谁协商 |
+//! | 跨中继 protobuf 分帧 | 没有。后端直接 TCP 连 `localhost:5173` |
+//! | 子路径 `/t/{slug}/` + 1000 行重写 | **一隧道一端口,路径 1:1**,重写代码为 0 |
+//! | 公开无认证入口 | 首访 token → cookie(见 `TunnelAccess`) |
+//!
+//! **一隧道一端口是「消除特殊情况」而不是省事**:挂子路径时 dev server 吐的
+//! `<script src="/assets/main.js">` 会打到隧道之外,所以必须重写它发出的每一个
+//! URL——HTML 属性、CSS、以及运行时的 fetch/XHR/WebSocket。独立端口下这个
+//! 绝对路径本来就是对的,整类问题不存在。
+//!
+//! ## 本模块的边界
+//!
+//! 这里只有**状态**:规格的增删改查、过期清理、健康探测结果。真正监听端口、
+//! 转发 HTTP/WS 的数据面在 `backend`——它需要 axum,而 backend 不能
+//! 碰 axum(会把 HTTP 服务器拖进核心库)。两者靠 `TunnelDataPlane` trait 对接。
+//!
+//! **端口由数据面分配**,不是 store。数据面从 bind 到 close 全程持有那个
+//! listener,所以不存在「探测到端口 → 释放 → 稍后重绑时已被抢走」的竞态。
+//!
+//! 数据流:`TunnelStore` 拥有全部状态 → 发 `tunnel:state` 事件到 EventBus →
+//! 前端(webview sink 或 WS sink)收到后重渲染。

+ * attempt that ends in error before committing, classified retryable by
+ * pi-ai's `isRetryableAssistantError`, is discarded wholesale and replaced by
+ * a fresh `factory()` call after a codex-style backoff — the caller never
+ * sees the failed attempt's events. Once committed, or once retries are
+ * exhausted/disabled, events pass straight through untouched. `onRetry` /
+ * `onRetryRecovered` let callers surface an ephemeral "reconnecting" status
+ * in place of the frozen UI, mirroring codex's TUI behavior.
+ *
+ * The pump below runs eagerly (not gated on the returned stream being
+ * iterated) because pi-ai's own stream factories start their network work as
+ * soon as they're called, independent of consumer iteration — some callers
+ * only await `.result()` without ever iterating events, and that pattern must
+ * keep working through this wrapper.
+ *
+ * This is the only retry layer, not a second one stacked on the library's:
+ * pi-ai builds its SDK request options with `maxRetries: options?.maxRetries ?? 0`
+ * (dist/api/{anthropic-messages,openai-completions,openai-responses}.js; the
+ * Google path has no retry at all), so SDK-level retries stay off unless a
+ * caller opts in — and `streamByApi` never does. It only forwards
+ * `maxRetryDelayMs`, which makes the SDK fail fast on long server-requested
+ * delays precisely so this layer can retry them with user-visible status.

     'Manage SSH sessions and remote SFTP files for SSH hosts explicitly associated with the current project. Use host_id from list_hosts. If list_hosts reports credential=saved, LiveAgent already has the configured password/private key/passphrase; do not ask the user to paste credentials into chat, and call create_session, exec, or SFTP actions directly. If list_hosts reports credential=missing, ask the user to configure credentials in Settings > SSH instead of requesting secrets in chat. If list_hosts reports credential=interactive, the host uses keyboard-interactive login: SSHManager never connects such hosts itself — create_session fails, and exec/SFTP only reuse a session the user already opened; if none is running, ask the user to connect in the SSH Tunnel tab first. Default session strategy is reuse_or_create: exec and SFTP reuse the same running session for that host before LiveAgent creates a visible session.

Use this whenever you need a decision only the user can make: ambiguous requirements, mutually exclusive approaches, or trade-offs you cannot resolve from the conversation and the workspace.
+
+The questions render as an interactive card; execution pauses until the user answers every question, then the selections come back as the tool result. If the user does not answer within ${ASK_USER_QUESTION_TIMEOUT_MINUTES} minutes, the recommended (or first) option of every question is auto-selected and execution continues — the result text tells you which happened.
+
+Rules:
+- Ask 1-${ASK_USER_QUESTION_MAX_QUESTIONS} focused questions per call; each question needs ${ASK_USER_QUESTION_MIN_OPTIONS}-${ASK_USER_QUESTION_MAX_OPTIONS} options (3-4 is ideal), and every question in one call must have the SAME number of options.
+- Options must be short, concrete, and mutually exclusive. Set recommended=true on your suggested choice (at most one per question) — it is shown first and becomes the timeout fallback.
+- The UI automatically appends an "Other" free-text option to every question, so the user can always type their own answer. Do NOT add your own catch-all option (e.g. "Other", "Custom", "其他", "自定义"). When the user types an answer, the result marks it as user-typed and returns their exact words instead of a listed label — treat it as authoritative.
+- Give each question a short header (2-6 chars works best) — it becomes the tab label when several questions show at once.
+- Do not use this for questions answerable from the code or the conversation, and never ask for confirmation of work you can safely do.`;

+# frontend tests
+
+All new project-level tests live under `crates/frontend/test` and are split by feature area:
+
+| Directory | Coverage |
+| --- | --- |
+| `settings/` | Settings normalization, provider routing, hooks, cron, MCP, remote config |
+| `chat/` | Uploaded files, UI message rounds, seed tool recovery, conversation segments |
+| `providers/` | Proxy URL validation, provider payload hooks, caching, storage metadata |
+| `tools/` | Workspace-relative path validation and custom system tool registration |
+| `i18n/` | Locale normalization and translation key parity |
+| `backend/` | Cargo smoke test that runs the existing Tauri backend unit suite |
+
+Run everything from `crates/frontend`:
+
+```sh
+pnpm test

 ## 项目一句话
 
-LiveAgent 是一个以桌面端为本地执行核心的 Agent 应用：GUI 负责用户体验与本地工具执行，Tauri/Rust 负责系统能力与持久化，Go Gateway 负责远程连接与协议中继，WebUI 通过 Gateway 操作同一个本地 Agent 会话。
+LiveAgent 是一个后端持有全部能力、前端只做渲染的 Agent 应用：Rust 后端（`backend` + `backend`）提供唯一的网络入口和全部本地能力，Node 引擎（`core`）跑对话循环，一份前端代码经 HTTP + WebSocket 连上去——不管它跑在 Tauri 桌面壳里还是浏览器里。

+# 后端边界
+
+本文件是「统一网络通信」重构的**第一交付物**。它把当前 234 个 `#[tauri::command]` 分成三类,
+决定哪些进入 `crates/backend`(独立进程、禁 tauri 依赖)、哪些永远留在 Tauri 壳、哪些直接删除。
+
+**这份分类是后续所有阶段的前提。** 分错一个,后端就会被迫 `use tauri::`,headless 模式编译不出来。

+## 划分标准

+| 判据 | 归属 |
+|---|---|
+| 读写数据、执行计算、操作文件系统/进程/网络 | **后端** |
+| 在某台机器的**图形界面上产生可见效果**(原生对话框、文件管理器、托盘、窗口、通知、全局快捷键、系统剪贴板) | **前端专属** |
+| 只为「桌面端主动拨向公网 Gateway」这一拓扑而存在 | **删除** |
+
+判断口诀:远程模式下,这个 command 在**后端那台机器**上执行还有意义吗?
+`system_pick_folder` 会在服务器上弹一个你看不见的对话框 —— 那它就是前端专属。

+## A. 后端(195)

+进 `crates/backend`,同时暴露为 HTTP/WS JSON API。前端与 Node 引擎都是它的客户端。
+
+| 模块 | 数量 | 备注 |

+| **`tunnel`** | **5** | 从 gateway 模块救回并重写,见下 |
+| **`provider_usage`** | **2** | 从 gateway 模块救回,见下 |
+| **`workspace_watch`** | **1** | 从 gateway 模块救回,见下 |
+
+### 从 gateway 模块救回的 8 个
+
+`commands/integration/gateway.rs` 里注册了 28 个 command,但其中 8 个**与中继拓扑无关**,
+只是恰好登记在这个文件里。它们是真实产品功能,必须进后端:
+
+| Command | 实际做什么 | 依据 |
+|---|---|---|
+| `workspace_watch_set` | 工作区文件监听 | `gateway.rs:299` 只调 `workspace_watch.set_desired(WatchSource::Local, …)` |
+| `provider_usage_query` | 查 provider 用量 | `gateway.rs:18` 只调 `provider_usage_service.query()` |
+| `provider_usage_test` | 测试用量查询配置 | 同上 |
+| `tunnel_state` | 隧道列表 | ✅ P2-30 已重写并改名(原 `gateway_tunnel_state`) |
+| `tunnel_create` | 建隧道 | ✅ |
+| `tunnel_update` | 改隧道 | ✅ |
+| `tunnel_close` | 关隧道 | ✅ |
+| `tunnel_check` | 探测本地端口 | ✅ 改为同步等探活完成 |
+
+这三组在阶段 2 迁移时必须**脱离 `GatewayController`**,改为直接持有各自的 service。
+
+### 隧道要重写,不是照搬 —— ✅ 已完成(P2-30)
+
+隧道的用途是:agent 在工作机上起了个 dev server(如 `:5173`),用户想从浏览器看效果。
+
+- **旧**:桌面端把端口注册到公网 Gateway,Gateway 开 `/t/{slug}` 公开反代,并重写 HTML 属性、
+  CSS `url()`、注入 shim、改 CSP(`internal/server/tunnel_rewrite.go` 424 行 +
+  `tunnel_proxy.go` 781 行)。
+- **新**:后端**就在**那台工作机上,且已有网络接口,直接反代到 `localhost:5173`。
+  **slug 注册协议、跨中继分帧、公开无认证入口全部不需要。**
+
+**「路径前缀重写是否必要」已定案:不必要,因为不挂子路径。** 每条隧道占一个独立端口,
+路径 1:1 —— dev server 发的 `<script src="/assets/main.js">` 本来就是对的。挂
+`/t/<id>/` 才需要重写它发出的每个 URL,那等于把上面那 1,205 行用 Rust 重写一遍。
+
+认证改为「首访 `?t=<token>` → HttpOnly cookie → 302 到干净路径」:浏览器标签页发不了
+`Authorization` 头,所以后端密码在这里用不上。强度与旧架构的「不可猜 slug」相当,
+但端口可被扫到而 token 不能。
+
+命令名已从 `gateway_tunnel_*` 改为 `tunnel_*`,事件 `gateway:tunnel-state` →
+`tunnel:state`。详见 [migration/phase-2-backend.md](migration/phase-2-backend.md#隧道重写p2-30)。
+
+### 后端专属但当前由前端触发的
+
+| Command | 说明 |
+|---|---|
+| `system_begin_power_activity` / `system_end_power_activity` | 阻止系统休眠。语义上属于**执行侧** —— 该阻止休眠的是跑任务的那台机器,不是看屏幕的那台。远程模式下前端调它毫无意义。归后端。 |
+
+### 落库时机(影响阶段 3)
+
+`chat_history_upsert_active_segment` / `chat_history_append_segment` 目前**只在 turn 结束时被调用一次**
+(`runAgentConversationTurn.ts:1217`,位于 1231 行函数的末尾)。
+
+阶段 3 之后引擎在后端,「断线重连拉快照」的快照源**必须是引擎内存态**(含正在生成的半条消息),
+不能查 SQLite,否则重连会看到会话回退到上一轮结束。详见方案风险 2。
+
+---
+
+## B. 前端专属(18)
+
+永远留在 Tauri 壳,**不进后端**。浏览器形态下用运行时探测降级或禁用。
+
+| 模块 / Command | 数量 | 理由 |
+|---|---|---|
+| `app::*` | 7 | 窗口行为、置顶、全局快捷键、退出确认、macOS 红绿灯位置、平台探测 —— 全是窗口/OS 级 |
+| `update::*` | 3 | `app_update_check` / `app_update_install` / `app_restart`,更新的是桌面客户端自身 |
+| `tray::app_tray_menu_sync` | 1 | 系统托盘 |
+| `system_pick_folder` | 1 | `FileDialog::new()` 原生对话框(`system.rs:1338`) |
+| `system_pick_file` | 1 | 同上 |
+| `system_pick_readable_files` | 1 | 同上 |
+| `system_clipboard_read_text` | 1 | 系统剪贴板;浏览器用 `navigator.clipboard` |
+| `fs_open_workspace_path` | 1 | 调系统文件管理器打开路径 |
+| `git_open_system_file_location` | 1 | 同上(`git.rs:3369`) |
+| `open_chat_file_link` | 1 | **需拆分**,见下 |
+
+### `open_chat_file_link` 必须拆开
+
+`chat_file_links.rs:628` 是个混合体。`:431` 处有分支:
+
+```rust
+if inside_workspace && !open_in_file_manager { … }
+```
+
+- 文件在工作区内且不要求文件管理器 → 返回 `ChatFileLinkOpenResponse { action, kind, workdir, path, line, … }`,
+  由前端在应用内打开。**这半边是纯解析,属于后端。**
+- 否则 → 调 OS 打开外部编辑器/文件管理器。**这半边属于前端。**
+
+阶段 2 拆成:后端 `chat_file_link_resolve`(返回 action + 定位信息),前端按 action 决定
+应用内跳转还是调 `plugin-opener`。
+
+上表按「含 OS 副作用」计入前端,拆分后后端会 +1、前端保持提供 OS 动作。
+
+---
+
+## C. 删除(21)
+
+只为「桌面端 outbound 拨向公网 Gateway」这一拓扑存在。新架构里前端主动连后端,这些全部失去意义。
+
+**连接管理(4)**
+`gateway_connect` `gateway_disconnect` `gateway_status` `gateway_nudge_connection`
+
+**chat 中继记账(15)** —— 对应 Gateway 里那 ~3,800 行可靠性补丁的桌面端一侧
+`gateway_send_chat_ingress_batch` `gateway_commit_chat_checkpoint` `gateway_chat_claim_next`
+`gateway_chat_mark_started` `gateway_chat_mark_local_started` `gateway_chat_mark_local_cancelled`
+`gateway_chat_mark_queued_in_gui` `gateway_chat_complete` `gateway_chat_fail`
+`gateway_chat_cancel_request` `gateway_chat_heartbeat` `gateway_chat_runtime_heartbeat`
+`gateway_chat_release_lease` `gateway_chat_queue_respond` `gateway_publish_chat_queue_event`
+
+**同步推送(1)**
+`gateway_publish_settings_sync`
+
+**本地代理自举(1)**
+`services::proxy::proxy_get_server_info` —— 现在返回本地 axum 的 `base_url` + 随机 `token`
+(`services/proxy.rs:97`),让前端知道去哪调 `/image-proxy` 和 `/proxy/{provider}`。
+新架构下前端本来就持有后端的 `baseUrl` + 密码,这层自举多余;
+且阶段 3 之后引擎在后端直连 provider,`/proxy/{provider}` 对前端也不再需要。
+
+> 这一条是本次统计新发现的 —— 它不在 `commands::` 命名空间下,
+> 按模块前缀过滤的清点方式会整条漏掉。
+
+上述 21 个连同 `services/gateway/*.rs`(~4,000 行)、`services/gateway_bridge.rs`(~1,400 行)
+在阶段 4 一并删除。
+
+---
+
+## 编译期防线
+
+分类靠自觉守不住。`crates/backend/Cargo.toml` **不得出现任何 tauri 依赖** ——
+一旦有人把前端专属 command 挪进后端,`cargo build -p backend` 直接失败。
+
+这是方案风险 4 的唯一对策,不要用文档约定代替。
+
+## 交叉引用
+
+- 总体方案与 19 项决策:`/Users/realm/.claude/plans/go-gateway-git-go-peaceful-wigderson.md`
+- 当前 Gateway 职责(将废弃):Gateway 已随阶段 6 删除,`docs/architecture/gateway.md` 不再存在
+- 当前整体架构(将重写):`docs/architecture/overview.md`(已按三层结构重写)

+# backend 拆分与 backend API 设计
+
+配套文档:`backend-boundary.md`(234 个 command 的三分类)。
+本文件记录**怎么拆**和**HTTP/WS 长什么样**。
+
+## crate 布局
+
+```
+crates/
+  backend/          后端核心 · Cargo.toml 禁 tauri（编译期防线）
+  backend/       axum HTTP/WS 服务 · 依赖 backend · 175 条路由 + /api/events
+  frontend/src-tauri/ 桌面壳 · 依赖 backend + backend（隧道数据面）
+                       · 只剩 #[tauri::command] 薄包装 + 托盘/窗口/更新
+```
+
+两个 crate 均已建立并接通,`cargo tree` 对 backend / backend 都零 tauri。
+
+桌面壳依赖 backend 只为复用隧道数据面(`TunnelDataPlane`)——两边跑同一份
+实现,行为不可能不一致。这不构成环:backend 不依赖 src-tauri。
+
+## 路由约定:命令式,不做 REST 化
+
+**决定:`POST /api/<command_name>`,body 是原样的参数 JSON。** 流式端点是唯一例外,走 WS。
+
+```
+invoke("git_status", { workdir })   →   POST /api/git_status   { "workdir": "..." }
+```
+
+理由 —— 前端**现在**就在用这些命令名和这些参数对象(`#[tauri::command]` 的参数名
+就是 JSON key)。1:1 映射让阶段 4 的前端迁移是机械替换;REST 化等于做 195 次独立
+设计决策,每次都是一个破坏前端的机会。这是「消除特殊情况」而不是「制造 195 个」。
+
+> 三份并行设计各自给出了不同约定(命令式 `/api/git_status`、kebab 资源式
+> `/api/terminal/{id}/ssh-local-forward`、REST 式 `/api/conversations`)。
+> 采纳命令式,理由如上。
+
+**`rename_all` 的坑**:部分命令写了 `#[tauri::command(rename_all = "snake_case")]`,
+部分没写(默认 camelCase)。HTTP 层必须**逐命令**沿用各自现有的约定,不能统一,
+否则前端字段名对不上。已知不一致:`git_clone_repository_tasks`、
+`chat_history_replace_from_message`。迁移时逐个核对,不要想当然。
+
+## 已核验的事实(实验或读源码确认,非推断)
+
+### `tauri::async_runtime` → `tokio` 的替换是安全的,但有前提
+
+读 `tauri-2.11.5/src/async_runtime.rs` 确认:
+
+| 项 | 结论 |
+|---|---|
+| 底层实现 | 纯 tokio。`JoinHandle` 是单变体枚举包 `TokioJoinHandle`(`:139`) |
+| 错误类型 | **不完全相同**。`impl Future for JoinHandle` 的 `Output = crate::Result<T>`,即 `Result<T, tauri::Error>`,经 `map_err(Into::into)` 从 `JoinError` 转来(`:164-169`)。但 `tauri::Error::JoinError(#[from] tokio::task::JoinError)`(`error.rs:73`),所以现有的 `.map_err(\|e\| format!("...{e}"))` 照常编译,只是 Display 文案略变 |
+| **runtime 前提** | **有实质差异**。`default_runtime()` 会 `TokioRuntime::new().unwrap()` **自建 runtime**(`:222-229`),所以 tauri 版在任何上下文可调;`tokio::spawn` 在 runtime 之外**会 panic** |
+
+逐站点核查结果:后端所有 `async_runtime::spawn*` 都只从 async 上下文可达
+(`scheduler.rs` 的 5 个同步 fn —— `start`/`report_task_error`/`start_fire`/
+`disable_task_detached`/`record_run_detached` —— 调用方都在 `async fn fire`/
+`execute_fire` 内;`spawn_ssh_reconnect_runner` 的 3 个调用点都在 async fn 内)。
+`registry.rs` 的 2 个裸 `thread::spawn`(PTY 读线程)**不碰** async runtime。
+
+唯一例外:`services/proxy.rs:83` `pub fn start_proxy_server()` 是同步 fn 且从
+Tauri `.setup()` 调用。但该文件正好被 backend 取代
+(`proxy_get_server_info` 已在删除清单),自然消失。
+
+**结论:可以机械替换。**
+
+### `include!()` 不是 blocker
+
+代码里有 50 处 `include!()`(`chat_history/`、`settings/`、`memory/` 三处把子文件
+摊平进同一模块)。实验验证(嵌套 `include!` + 独立 crate + 跨 crate 引用):
+
+- ✅ `include!` 路径相对于**宏调用所在的物理文件**,与 crate 边界无关。整目录搬迁保持
+  相对布局即可,编译通过。现有代码本身就是证据:`settings/mod.rs` 里
+  `include!("ssh/mod.rs")`,而 `ssh/mod.rs` 里 `include!("load.rs")` 解析到 `ssh/` 目录。
+- ⚠️ 真正的问题是 **`pub(crate)` 跨 crate 变私有**(`E0603`),而 `include!` 把所有文件
+  摊平进一个模块,放大了这个面。
+
+待迁移代码有 580 处 `pub(crate)`,但**留在壳里的代码只引用 29 个不同符号路径**。
+所以不要批量提升为 `pub`,只提升真正跨界的那些——其余保持 `pub(crate)`
+(在 backend 内部依然有效)。
+
+## 已决的设计决策
+
+| 问题 | 决策 | 理由 |
+|---|---|---|
+| `tauri::State` 注入的命令会话隔离（P2-24） | **不做 owner 命名空间，id 即隔离边界** | 三个 registry（`GitCloneTaskRegistry`/`ShellRunRegistry`/`HookScopeRegistry`）都按调用方提供的字符串 id keyed（`task_id`/`run_id`/`scope_id`），且 task id 是服务端 UUID 天然不可猜。桌面壳本就允许 Gateway 与 GUI 共享同一批 registry。决策 7 下所有客户端共享同一密码、没有客户端身份，owner 维度无从谈起。HTTP 侧与桌面现状一致 |
+| 返回 `Result<(), String>` 的命令状态码（P2-25） | **保持 200/400 两档** | 与 Tauri IPC 语义一致（Err 就是失败），错误体已带字符串，前端在读。补 404/403 需要逐命令审计错误来源，收益有限 |
+| 隧道数据面挂在哪（P2-30） | **一隧道一端口，路径 1:1**，不挂子路径 | 挂 `/t/<id>/` 时 dev server 发的绝对路径会打到隧道外，必须重写 HTML/CSS/fetch/WS 并改 CSP（Go 版 1,205 行）。独立端口下这类问题不存在，重写代码 0 行 |
+| 隧道端口怎么保护（P2-30） | **首访 `?t=<token>` → HttpOnly cookie → 302 到干净路径** | 浏览器标签页发不了 `Authorization` 头，后端密码在这里用不上。与旧架构的「不可猜 slug」同强度，但端口可被扫到而 token 不能 |
+
+## 待解决
+
+阶段 2 的待解决项已全部闭合。
+
+> 已闭合：`GatewayEventSink` 测试 → `action_for` 纯函数 + 变异验证（P2-14）；
+> EventBus 背压 → WS sink 自排队 + 丢帧（容量 256，非阻塞 `tx.send`）；
+> 3 个 settings 命令 → 已随 175 条路由生成；
+> axum 0.8 TLS → `RustlsConfig::from_pem_file` 已查证并实现（P2-22）；
+> 隧道重写 → P2-30；不经前端实测 → P2-31。

+# 前端架构
+
+## 定位
+
+**只有一个前端源码树**：`crates/frontend/src`。阶段 5 把 `agent-gateway/web`
+（126,934 行）整个删掉，以 GUI 为基线合并（决策 16）。
+
+同一份代码跑在两种宿主里：
+
+| 宿主 | 后端在哪 | 登录页 | 壳能力 |
+|---|---|---|---|
+| Tauri 桌面壳 | 壳在进程内启动，`127.0.0.1:<随机端口>` | 跳过 | 全部可用 |
+| 浏览器 | 用户填的地址，可能在别的机器上 | 需要 | 隐藏或降级 |
+
+差异**不靠构建分叉**，靠运行时探测。判定源头只有一个：`isDesktopShell()`。
+
+## 模块地图
+
+| 模块 | 路径 | 职责 |
+|---|---|---|
+| App shell | `src/App.tsx` | 设置 hydration/save、主题/i18n、Settings overlay、ChatPage、CronPromptRunner、MemoryOrganizerRunner、全局 toast |
+| 登录门禁 | `src/pages/login/` | `AuthGate` + `LoginPage` + `probeEndpoint` |
+| Chat 页面 | `src/pages/ChatPage.tsx`、`src/pages/chat/*` | 会话状态、发送/取消、历史、上传、模型选择、审批卡片、压缩状态 |
+| Settings | `src/pages/SettingsPage.tsx`、`src/pages/settings/*` | Providers、System、MCP、Agents、Hooks、Cron、Remote、Memory、Skills |
+| Hub 页面 | `src/pages/skills-hub/*`、`src/pages/mcp-hub/*` | Skills Hub、MCP Hub、store/registry 浏览 |
+| UI 组件 | `src/components/*`、`src/components/ui/*` | Sidebar、Markdown、git、memory、cron、project-tools、workspace-editor 等 |
+| **后端客户端** | `src/lib/backend/*` | 端点解析、HTTP + WS 传输、命令/事件分流、Tauri API 顶替 |
+| 壳能力探测 | `src/lib/shell/capabilities.ts` | 七个语义化谓词 |
+| 领域库 | `src/lib/{settings,skills,memory,terminal,sftp,git,tools,mcpRegistry,tunnels,…}` | 各功能域的前端侧逻辑 |
+
+**`src/lib/providers`、`src/lib/chat`、`src/lib/tools` 已不再承载对话运行时**——
+引擎在 `crates/core`。前端保留的是渲染、设置与工具目录展示所需的部分。
+
+## 后端客户端（`src/lib/backend/`）
+
+这是整个前端唯一的对外出口。七个文件，各管一件事：
+
+| 文件 | 职责 |
+|---|---|
+| `endpoint.ts` | 端点从哪来（壳注入 / URL 参数 / localStorage）、凭据存取、`isDesktopShell()` |
+| `transport.ts` | **真正的传输层**：`fetch` 打命令、一条 WS 收事件、重连退避 |
+| `client.ts` | `backendFetch` / `backendFetchGet` / `subscribeEvents` 的显式命名面 |
+| `commandRouting.ts` | 哪些 command/event 走壳、哪些走网络 |
+| `tauriCore.ts` | vite alias 顶替 `@tauri-apps/api/core`，`invoke()` 落到这里分流 |
+| `tauriEvent.ts` | 同上，顶替 `@tauri-apps/api/event` 的 `listen`/`emit` |
+| `tauriShim.ts` / `tauriOpener.ts` | 浏览器侧的 internals polyfill 与 `plugin-opener` 顶替 |
+
+业务代码**继续写 `invoke("chat_history_list")`**，不需要知道它落到哪。这是阶段 4
+的核心手法：分流只有一个判定处，新增后端 command 不需要改任何名单。
+
+### 端点解析
+
+```text
+桌面壳   → invoke("get_backend_endpoint")  → {host: "127.0.0.1", port, password}
+浏览器   → URL 参数 ?backendHost=&backendPort=&token=&secure=
+         → 否则 localStorage["liveagent.backend.endpoint"]
+         → 都没有 → MissingCredentialsError → 登录页
+```
+
+壳内嵌的后端是 `.setup()` 里 spawn 的，前端跑起来时它可能还没监听。
+`askShellForEndpoint()` 退避重试到拿到为止（上限 30s）。**shim 的安装必须是同步
+的，但所有真正的调用都 `await` 同一个 Promise**——于是「端点未就绪期间的调用」
+自然排成队列，不需要额外的队列结构。
+
+URL 参数优先并顺手持久化，所以「发一条链接就能连上远程后端」不必先过登录页。
+
+### 传输
+
+| 方向 | 实现 |
+|---|---|
+| 命令 | `POST {base}/api/<command>`，`Authorization: Bearer <password>` |
+| 快照 | `GET {base}/api/<command>?…`（`conversation_live` 一类） |
+| 事件 | 一条 `WebSocket {wsBase}/api/events?token=…`，全局共享 |
+
+响应解析：`routes_gen` 的 `respond()` 统一包 `{ok: …}`，`engine_proxy` 的快照类
+GET 不包。**有就拆，没有就原样给**——比「没有 ok 字段就报错」少一类假故障。
+401/403 抛 `UnauthorizedError`，登录页据此提示「密码不对」而不是笼统的「连接失败」。
+
+WS 重连：500ms 起指数退避、上限 10s；**全局只允许一个待触发的定时器**。订阅者有
+十几个（每个 `listen` 都会调 `ensureSocket`），不去重的话退避链会成倍增长，后端
+没起来时前端会拿几十条重连打自己。
+
+## 登录与认证
+
+| 阶段 | 行为 |
+|---|---|
+| 壳内 | `AuthGate` 直接渲染 App，**一次网络探测都不做**。没有闪屏，没有登录页（决策 8） |
+| 浏览器无凭据 | 直接进登录页 |
+| 浏览器有凭据 | 先 `probeEndpoint()` 探一次，把「密码过期」「填成了旧 Gateway 地址」「后端没起来」三种情况分辨清楚，否则用户看到的是应用加载后满屏失败的请求 |
+| 旧版痕迹 | localStorage 里有 `liveagent.gateway.token` 时给 v2 迁移提示 |
+
+密码就是 Bearer token，前端不做任何变换。
+
+## 宿主差异清单
+
+`src/lib/shell/capabilities.ts` 的七个谓词当前**全部等价于 `isDesktopShell()`**。
+分开命名是给调用点说清语义、给将来判定分化（比如 Linux 无托盘）留位置，
+不是七个不同实现。
+
+| 能力 | 浏览器里的处置 |
+|---|---|
+| 系统托盘 | 入口隐藏 |
+| 自更新 | 入口隐藏（浏览器版本随后端走） |
+| 窗口控制（置顶/关闭行为/macOS 红绿灯） | 入口隐藏，调用点早退 |
+| 全局快捷键 | 入口隐藏 |
+| 剪贴板 | 降级 `navigator.clipboard`（`clipboardText.ts` 本就有兜底） |
+| 外链打开 | 降级 `window.open`（`tauriOpener.ts` 经 vite alias 顶替插件，7 个 import 点零改动） |
+| 上传选文件 | 降级 `<input type=file multiple>`，产出与 `system_pick_readable_files` 等价的结构 |
+| **原生"浏览…"对话框** | **隐藏按钮，保留手输路径** |
+| 打开系统文件位置 | 入口按 `hasSystemFileOpener()` 隐藏 |
+
+**为什么"浏览…"不降级**：`system_pick_file` / `system_pick_folder` 选的是**后端
+所在机器**上的路径。桌面壳里前端和后端同机，弹原生对话框是对的；浏览器连远程
+后端时，弹浏览器对话框选到的是用户本机路径，对后端毫无意义。降级成
+`<input type=file>` 是语义错误，所以不做。
+
+隐藏按钮的连带损伤已排查：`WorkspaceCloneModal` 的父目录输入框原本 `readOnly`、
+只能靠原生对话框填，藏按钮时已改条件式 `readOnly`。
+
+## Chat 在前端这一侧
+
+引擎在后端，**前端只是渲染**（决策 10）。ChatPage 的编排范围因此小了很多：
+
+| 环节 | 前端做什么 |
+|---|---|
+| 发送 | `backendFetch("chat_send", {conversationId, text, …})`，拿 202 就结束 |
+| 增量 | `useBackendEventSubscription` 订阅 WS，按 `conversation_id` 路由到对应的 `LiveTranscriptStore` |
+| 取消 | `backendFetch("chat_abort", {conversationId})` |
+| 恢复 | 切换会话 / 重连时 `backendFetchGet("conversation_live", {conversationId})` 拉引擎内存快照；404 当作「无 live 增量」，基线走历史命令 |
+| 审批 | 收到 `tool-approval:request` 事件 → 渲染卡片 → `backendFetch("tool_approval_respond", {approval_id, decision})` |
+| 历史 | `chat_history_*` 命令，与其他后端命令没有区别 |
+
+前端不再持有 provider API key，也不再需要脱敏快照那一套——密钥在后端。
+
+## 已知遗留
+
+| 项 | 状态 |
+|---|---|
+| `src/pages/chat/gateway/` | 7 个文件仍在（`useGatewayBridgeListeners` 等）。Rust 侧的 `gateway_*` command 已删，`commandRouting.ts::REMOVED_GATEWAY_COMMANDS` 本地拦下这 21 个调用并给迁移提示，避免用户看到 "command not found" / 404 这类让人猜的错误 |
+| `openChatFileLink` | 浏览器里是「报错」不是「隐藏」。聊天消息里的文件链接是内联渲染元素，没有可门控的菜单入口，点击弹一句中文错误。真隐藏要在渲染层把链接降级成纯文本，改动大收益小 |
+| 门控实测 | 全部门控是静态推导 + tsc 保证，**未在真浏览器里逐项点过**（阶段 5 验收未跑完） |
+
+## 测试
+
+```bash
+node --test 'crates/frontend/test/**/*.test.mjs'
+```
+
+1371 个测试。行为型测试走 `helpers/load-ts-module.mjs`，用 `vm` 真实执行 TS，
+断言输入输出。
+
+阶段 5 清理掉了 20 个「用 `readFileSync` + 正则断言源码文本」的脆测试
+（删 8、重写 2、裁剪 7、保留 3，**无一 skip**）——它们锁死源码长相而不验证行为，
+大规模重构时会成片红，且红了也不代表真有问题。同时清掉了所有「双跑
+GUI+WebUI 两份实现」的 parity 断言：web 树没了，比较对象也没了。
+
+## 设计取舍
+
+| 取舍 | 原因 |
+|---|---|
+| 分流用**反向**白名单 | 只列 19 个壳专属 command，其余一律走网络。正向列 176 行白名单意味着每加一个后端命令都要改前端 |
+| 顶替 Tauri API 而不是改调用点 | vite alias + tsconfig paths 让 57 个文件的 `invoke()` 零改动完成网络化 |
+| 全局一条 WS | 端点解析、鉴权、重连退避都只有一份，不会出现「两条连接各自退避」 |
+| 能力探测而不是构建分叉 | 两份代码必然漂移；`mirror-manifest.json` 那套 CI 逐字节校验就是漂移的代价，已随合并删除 |
+| ChatPage 仍是编排中心 | 即使引擎搬走了，会话状态、上传、模型选择、审批 UI 仍需要一个汇聚点 |

-# Go Gateway 架构
-
-## 职责边界
-
-Gateway 是远程访问中继，不是 Agent 执行环境。它同时面对桌面 Agent 和浏览器 WebUI，
-两端统一走 WebSocket+Protobuf（v2 协议）：
-
-| 方向 | 协议 | 作用 |
-|---|---|---|
-| Desktop Agent -> Gateway | WebSocket `/ws/v2/agent`（Protobuf 帧） | 桌面端注册在线 session，接收 WebUI 请求（`GatewayEnvelope`），返回 chat/history/settings/memory/skills 等响应与事件（`AgentEnvelope`）。 |
-| Desktop/Browser -> Gateway | WebSocket `/ws/v2/terminal`（Protobuf 帧） | 专用终端字节流（角色由 hello 区分），承载 attach snapshot、input、resize、output，不与普通控制面共享队列。 |
-| WebUI -> Gateway | WebSocket `/ws/v2`（Protobuf 帧） | 浏览器端发起 chat（command/subscribe）、直通 history/settings/skills/memory/cron 等请求，并订阅 `chat_event` 与同步广播。 |
-| WebUI -> Gateway | HTTP `/api/*` | 状态检查、文件上传、公网分享页、图片代理、静态资源。 |
-
-## 入口与服务启动
-
-| 文件 | 作用 |
-|---|---|
-| `cmd/gateway/main.go` | 读取 config，创建 `session.Manager`，启动 HTTP server，处理 shutdown。 |
-| `internal/config/config.go` | 地址、token、TLS、静态资源、请求大小、超时等配置。 |
-| `internal/observability/` | slog 初始化与 v2 协议使用计数（`/api/status` 的 `protocol_usage`）。 |
-| `internal/transport/wscore/` | WebSocket 连接运行时：控制优先双队列写泵、拥塞掉帧、有限重试、心跳与空闲驱逐。 |
-| `internal/protocol/pbws/` | **v2 协议层**：三链路握手/编解码、直通白名单（`guard.go`）、关联 id 命名空间化、事件扇出与快照回放。 |
-| `internal/protocol/shared/` | 协议无关的域逻辑：Origin 校验、终端权限门控与响应后处理、终端兴趣跟踪。 |
-| `internal/chatcmd/` | chat 命令编排（归一化、探活、投递、启动看门狗）。 |
-| `internal/auth/` | HTTP/WS token 校验。 |
-| `internal/server/http.go` | HTTP mux、v2 WebSocket 路由、API、静态 WebUI 与 public share route（proto→JSON 塑形见 `proto_json.go`）。 |
-| `internal/session/manager.go` | `session.Manager` façade 和核心公开类型（transport 无关）。 |
-| `internal/session/manager_state.go` | session registry、sync hub、chat run store 的内部状态定义。 |
-| `internal/session/manager_registry.go` | 当前 Agent session、认证快照、per-request stream 注册。 |
-| `internal/session/manager_*_sync.go`、`manager_terminal.go`、`conversation_stream.go`、`conversation_ingress.go` | history/settings/terminal sync、进程内 Chat 事件窗口、实时 fan-out、replay 与 command dedupe。 |
-
-## HTTP 路由
-
-| 路由 | 认证 | 说明 |
-|---|---|---|
-| `GET /ws/v2` | hello token | **v2** WebUI 主链路（Protobuf 帧，子协议 `liveagent.v2.pb`）。 |
-| `GET /ws/v2/agent` | hello token | **v2** 桌面端信封流。 |
-| `GET /ws/v2/terminal` | hello token | **v2** 终端数据面（两端共用，角色在 hello）。 |
-| `GET /api/status` | token | Agent 在线状态 + `protocol_usage` 协议使用计数。 |
-| `POST /api/files/import` | token | WebUI 上传可读文件，Gateway 转发给桌面端写入 `~/.liveagent/uploads` 暂存区。 |
-| `GET /api/public/history-shares/{token}` | public token | 公开只读历史分享数据。 |
-| `GET /image-proxy` | 视配置/实现而定 | 图片代理，带 URL 安全校验。 |
-| `/` | 无或按静态资源策略 | 嵌入/构建后的 WebUI 静态资源与 SPA fallback。 |
-
-Chat 走 `/ws/v2` 且是严格新协议：`chat_prepare` 用关联 Ping/Pong 探测并唤醒桌面 Chat Runtime；`chat_command` 携带 proto `ChatCommandRequest`，`chat_subscribe` 按 `conversation_id` 订阅。旧 HTTP SSE 路由 `GET /api/chat/events` 已下线。
-
-## Proto 定义与代码生成
-
-`proto/v2/gateway.proto` 是三端共享的权威业务消息定义，`proto/v2/gateway_ws.proto` 定义 WebSocket 帧壳；Go 统一生成于 `internal/proto/v2/*`。代码生成统一由 `buf` 驱动（`make proto`），CI 有生成物漂移与 breaking 检查门禁。
-
-## Session Manager
-
-`session.Manager` 是 Gateway 状态 façade，对外维持原有 API；内部按职责拆成 session registry、sync hub 和 chat run store，避免一个锁覆盖所有状态。
-
-| 状态 | 说明 |
-|---|---|
-| session registry | 当前桌面 Agent session、认证快照、session epoch、per-request stream。 |
-| sync hub | history/settings/terminal 订阅者、settings 快照、terminal session snapshot。 |
-| conversation stream store | 当前进程内按 conversation 维护单调 `seq`、`stream_epoch`、活动 run、最近事件窗口与 subscriber；负责实时 fan-out 和短时 replay。 |
-| chat command dedupe | 当前进程内原子维护 `client_request_id -> canonical run`，保留 24 小时，并保存最新 `bound`/`queued_in_gui`/`failed` update 供 ACK 丢失后的重试连接 replay。 |
-
-## Chat 事件窗口与恢复
-
-| 机制 | 当前含义 |
-|---|---|
-| 有界内存窗口 | 每个 conversation 默认保留最近 10 分钟事件，硬上限 4096 条或约 8 MiB；活动 run 在未触及硬上限时不会因时间淘汰，空闲 conversation 约 30 分钟后回收。 |
-| `Seq` / `stream_epoch` | 同一 Gateway 进程内，`seq` 按 conversation 单调递增并跨 run；WebUI 用 `after_seq` 补收窗口内事件。epoch 不同、游标超前或事件已淘汰时返回 `reset`，客户端改用桌面历史 snapshot 重建。 |
-| command 幂等 | `StartChatCommand` 在同一 store mutex 下原子分配 canonical run；同一 `client_request_id` 的并发或重试提交返回同一 `run_id`，不会重复 seed 或 dispatch。记录保留 24 小时。 |
-| command update replay | Gateway 保存 canonical run 最新的 `bound`、`queued_in_gui` 或 `failed` update；WebUI ACK 丢失后重连并以同 ID 重试时，不会错过 pre-stream 结果。 |
-| 进程重启边界 | Chat 事件窗口与 command dedupe 都不跨 Gateway 进程持久化。Gateway 重启后由 WebUI history snapshot 与桌面端 run ledger/status republish 重新对账；跨重启不承诺 exactly-once。 |
-
-## WebSocket 协议角色
-
-| 类型 | 说明 |
-|---|---|
-| request/response | WebUI 发带 id 的 request，Gateway 返回同 id response 或 error。 |
-| broadcast | Gateway 主动推送 `status`、`history.event`、`settings.event`、`terminal`、`sftp` 等非 Chat 同步事件。 |
-| chat prepare | `chat.prepare` 向当前 `AgentConnect` stream 发送带 `chat-runtime-wake-` request id 的 Ping；桌面 Rust emit WebView wake 并可靠返回关联 Pong，Gateway 收到真实往返后才响应，并记录绑定当前 session epoch 的短时新鲜度。 |
-| chat command | 提交/编辑/取消走 WS `chat.command`；新 command 在 accepted 前必须有原生往返 probe，紧随成功 prepare 的 command 可复用同一 session 2 秒内的新鲜结果，旧客户端或过期结果仍现场探测。accepted ACK 走控制优先队列，避免被 token 数据积压阻塞。流式事件走按 conversation 持久订阅 `chat.subscribe`， 订阅与退订均按 `(agent_id, conversation_id)` 作用域并要求非空 `agent_id`，经 `chat.event` 推送（订阅缓冲溢出时发 `chat.subscription_reset` 提示客户端按游标重订阅）。 |
-| terminal stream | 不走主链路 request；attach/input/resize/detach 走 `/ws/v2/terminal` proto frame，页面侧 `BrowserGatewayTerminalStreamClient` 为同一 token 复用一条 terminal stream 并按 session fan-out。 |
-
-WebSocket server 的实现分层：`internal/transport/wscore` 管写泵/背压/心跳；协议层在 `internal/protocol/pbws`（帧编解码、直通白名单、事件扇出）。域逻辑（终端门控/响应后处理、chat 编排）在 `internal/protocol/shared` 与 `internal/chatcmd`。
-
-Terminal metadata 事件通过 `/ws/v2` 广播臂（`terminal_event`）同步 `created`、`exit`、`closed`、`renamed`、SSH prompt 和 SSH tab 状态；terminal output 不进入 React session state，也不附带完整 session。输出 bytes 只通过 `/ws/v2/terminal` 推送，慢客户端只阻塞自己的 terminal stream。
-
-## 安全模型
-
-| 领域 | 设计 |
-|---|---|
-| 认证 | HTTP API 通过 Bearer token；WebSocket 通过 hello token（辅以 Origin 校验）。 |
-| Chat command 防护 | Chat 命令仅经认证后的 WebSocket `chat.command` 提交（连接级 token + Origin 校验，2 MiB payload 上限）；accepted 前必须完成当前原生 stream 的关联 Ping/Pong。 |
-| Chat 订阅防护 | `chat.subscribe` 仅在认证后的 `/ws/v2` 连接上可用；每个 conversation 的 replay 受 4096 条与约 8 MiB 事件窗口硬上限保护。 |
-| Provider API key | 普通 settings sync 不应携带真实 key；WebUI 只接收 presence/redacted 字段。 |
-| 文件访问 | WebUI 上传只把 bytes 交给桌面端导入，Gateway 不直接落地为任意本地路径。 |
-| 工具执行 | Gateway 不运行 Shell、FS、MCP、Memory mutation 等高权限工具，只转发请求到桌面端。 |
-| Public share | 分享数据走 token 定位，支持只读 transcript，并可按设置 redaction tool content。 |
-| Public share error | 桌面端通过 `ErrorResponse.code` 返回 `history_share_resolve` 错误语义，Gateway HTTP 根据 code 映射 400/404/502 等状态，不再依赖错误文案判断。 |
-
-## Gateway 失败模式
-
-| 失败 | 表现 | 设计处理 |
-|---|---|---|
-| Desktop offline | WebUI 请求返回 agent offline 或状态 offline | `session.Manager` 检测当前 session，WebUI 展示离线/不可用状态。 |
-| WebSocket 断开 | WebUI 自动重连；Chat 订阅按 `after_seq` 游标恢复 | `GatewayWebSocketClient` 统一管理重连并在重连后重发 `chat.subscribe`，Gateway 从当前进程的有界事件窗口补发；窗口不足时返回 reset，由桌面历史 snapshot 重建。 |
-| 桌面端信封流断开 | Agent session close，pending stream 结束 | 桌面端 remote auto reconnect 可重新建立 session；重连后桌面端 republish chat run 台账（active `started` + 未确认终态控制事件），网关幂等收养。 |
-| 长时间空闲后首发 | socket、信封流或 WebView runtime 可能半开/休眠 | `chat.prepare` 在默认 2 秒内完成关联原生 Ping/Pong，紧随 command 复用 session-bound 新鲜结果；没有新鲜结果时 command 自行 probe。失败立即返回而不把命令错误标记为 accepted。 |
-| Chat run 终态信号丢失 | run 已在桌面端结束但网关 activity 未清除 | 桌面端 `ChatRunLedger` 先记账再发送，5s sweeper 重发未送达终态；心跳 `RuntimeStatusEvent.active_runs/finished_runs` 驱动网关对账：finished 报告按真实终态收养，active 报告逐 run 续命，缺席且无事件/续命超过 `runReportLostTimeout`（15s）判 `failed/desktop_run_lost`。 |
-| Chat run 卡死兜底 | 桌面端不再上报某 run | 在线走 `staleRunTimeout`（10min，逐 run 续命，单会话忙碌不屏蔽他会话）；离线走 `offlineRunTimeout`（30min）判 `failed/agent_offline`。 |
-| Chat run 重复提交 | 同一 Gateway 进程内，同一 `client_request_id` 重复 | 24 小时进程级原子去重返回 canonical run；用于覆盖 WebSocket ACK 丢失的一次同 ID 重试。 |
-| Chat command 未进入运行态 | 事件流只到 accepted/delivered 后不继续 | command path 使用默认 5 秒 `LIVEAGENT_GATEWAY_CHAT_START_TIMEOUT` 加 10 秒 `LIVEAGENT_GATEWAY_CHAT_RENDER_START_TIMEOUT` watchdog 写入 `run.failed`，避免 WebUI 无限等待。 |
-| 服务退出 | Ctrl+C 后 HTTP graceful shutdown | `cmd/gateway/main.go` 控制退出与超时。 |

-| 责任 | 当前实现 |
-|---|---|
-| 初始设置 | 通过 settings API 读取 providers/system/mcp/agents/hooks/cron/remote/memory，并与前端默认值合并。 |
-| 设置保存 | Settings 页修改后按配置域保存到 Tauri SQLite，并在需要时 publish settings sync 到 Gateway。 |
-| 主题与语言 | `theme` 写入 document root，`LocaleProvider` 提供翻译。 |
-| 页面布局 | 主视图以 ChatPage 为中心，Settings 使用 overlay/modal 风格进入。 |
-| 后台 runner | `CronPromptRunner` 接管 prompt 类型 cron；`MemoryOrganizerRunner` 接管自动整理记忆。 |
-| 远程桥接 | Remote settings 启用时，Tauri GatewayController 连接 Go Gateway，并把 settings/history/chat event 发布出去。 |
-
-## ChatPage 编排
-
-| 子系统 | 说明 | 关键路径 |
-|---|---|---|
-| 会话运行态 | 当前 conversation、session、message list、live stream、tool status、running/canceling 状态。 | `ChatPage.tsx`、`pages/chat/useChatPageRuntimeStore.ts`、`lib/chat/conversation/liveTranscriptStore.ts` |
-| 发送入口 | 将用户文本、附件、选中模型、execution mode、workdir、system tools 等合并为 turn request。 | `ChatPage.tsx` |
-| text 模式 | 只做模型文本流式，不注入本地工具。 | `pages/chat/runTextConversationTurn.ts`、`lib/providers/llm.ts` |
-| tools/agent-dev 模式 | 构造 builtin tools，执行模型 tool loop，写工具 trace，并同步 Gateway chat event。 | `pages/chat/runAgentConversationTurn.ts`、`lib/chat/conversation/run/*` |
-| 历史持久化 | V3 segment 写入 Tauri SQLite，支持 append segment、active segment update、rename/delete/pin/share。 | `lib/chat/conversationState.ts`、`src-tauri/src/commands/chat_history.rs` |
-| 上下文压缩 | 在 pre-send、mid-stream、post-tool 等阶段生成 summary checkpoint，避免超上下文。 | `pages/chat/conversationContextBuilders.ts`、`lib/chat/conversation/compaction/*` |
-| 记忆注入 | 每轮根据 workdir 读取 memory overview，并附加到 system prompt。 | `lib/chat/memory/memoryPrompt.ts`、`src-tauri/src/services/memory.rs` |
-| Skills 注入 | 根据 Settings Skills 选择与 always-on builtin skills 生成 skills prompt。 | `lib/skills/index.ts`、`pages/chat/useChatSkills.ts` |
-| 上传 | GUI 直接调用 Tauri import readable files/image preview；工作区外文件复制到 `~/.liveagent/uploads` 暂存区（不污染工作区），工作区内文件原地引用。 | `pages/chat/usePendingUploads.ts`、`src-tauri/src/commands/system.rs` |
-| Gateway bridge | 本地运行时接收远程 command，把 token/thinking/tool/done/error 等事件发布给 Gateway；listener 与 worker id 在组件生命周期内保持稳定。 | `pages/chat/gateway/useGatewayBridgeListeners.ts`、`lib/chat/conversation/run/gatewayBridgeEvents.ts` |
-
-## Tauri Invoke Surface
-
-`src-tauri/src/lib.rs` 用 `tauri::generate_handler!` 注册桌面端所有命令。按领域可归纳为：
-
-| 领域 | 命令族 |
-|---|---|
-| Chat history | `chat_history_list/search/get/upsert/upsert_active_segment/append_segment/rename/set_pinned/share_get/share_set/delete` |
-| Subagent store | `subagent_identity_upsert/list`、`subagent_run_save/list/load/prune`、`subagent_message_append/list` |
-| File system | `fs_read_text/read_image_source/write_text/edit_text/delete/list/glob/grep/mention_list` |
-| Subagent worktree | `subagent_worktree_create/status/apply/cleanup` |
-| MCP runtime | `mcp_list_tools/call_tool/runtime_status/stop_server/test_server/restart_server` |
-| Memory | `memory_list/read/search/write/update/delete/accept/apply_batch/organize_* /index_overview/paths_info/recent_rejections/today_daily/wipe_all` |
-| Settings | `settings_load_all/save_providers/save_system/save_mcp/save_agents/save_hooks/save_cron/save_remote/save_memory` |
-| Hooks/Cron | `hook_run_script/run_http_requests`、`cron_validate_expression/list_logs/clear_logs/take_pending_prompt_runs/complete_prompt_run` |
-| Shell/process | `shell_run/cancel`、`managed_process_start/status/stop/read_log` |
-| System | folder/file picker、uploads、skill metadata/text/manage、debug jsonl、power activity、cron task manage |
-| Gateway | `gateway_connect/disconnect/status/nudge_connection/send_chat_event/publish_conversation_activity/publish_settings_sync` |
-| Proxy | `proxy_get_server_info` |
-
-## Rust Services 与 Runtime
-
-| 路径 | 作用 |
-|---|---|
-| `src-tauri/src/services/gateway/*` | GatewayController，维护桌面端到 Gateway 的连接、原生唤醒、inbox、状态同步与重连。 |
-| `src-tauri/src/services/gateway_bridge.rs` | 将 Gateway 请求转成前端/Tauri 能处理的操作，处理 settings/history/chat 等桥接。 |
-| `src-tauri/src/services/memory.rs` | MemoryStore，负责 Markdown 记忆文件、SQLite FTS 索引、quota、daily、organizer。 |
-| `src-tauri/src/services/skills.rs` | Skills root、builtin seed、install/create/validate/package、ClawHub。 |
-| `src-tauri/src/services/cron.rs` | CronManager，调度 bash/http/prompt task，记录日志并暴露 pending prompt run。 |
-| `src-tauri/src/services/proxy.rs` | 本地 proxy server，用于 provider proxy 和上游访问。 |
-| `src-tauri/src/runtime/shell_runner.rs` | Shell 脚本执行抽象。 |
-| `src-tauri/src/runtime/managed_process.rs` | 长任务/后台进程管理。 |
-| `src-tauri/src/runtime/task_runner.rs` | 通用异步任务运行辅助。 |
-
-## Gateway 连接与 Runtime 唤醒
-
-| 机制 | 当前实现 |
-|---|---|
-| 稳定 WebView listener | `useGatewayBridgeListeners` 用 ref 保存 worker id 和最新回调，effect 只在组件挂载/卸载时注册或销毁；普通 React render 不再重建 listener、制造接收空窗或重复上报 `suspended`。 |
-| 原生往返唤醒 | Rust 收到 `chat-runtime-wake-` 前缀的关联 Ping 后 emit `gateway:chat-runtime-wake`；所有 Pong（唤醒与心跳）经专用出站控制通道（64 深，与数据队列 merge 进同一信封流（v2 WebSocket））`try_send` 返回，token 流打满数据队列时探测仍可被应答，且绝不阻塞 inbound receive loop。 |
-| 生命周期 nudge | `online`、`focus`、`pageshow`、`visibilitychange`、WebView `resume` 与 Tauri `RunEvent::Resumed` 会唤醒 runtime；`online`/focus 类事件经 `gateway_nudge_connection` 走 offline/stale-heartbeat 健康检查后才重建连接（不强制），仅 `RunEvent::Resumed` 保留强制重连。 |
-| 快速重连 | 信封流自动重连从 250ms 指数退避到 5s（v2 `/ws/v2/agent`），稳定连接 30s 后重置；stale 判断使用 heartbeat interval 加 20s（最多 60s）。 |
-| inbound 优先 | 信封流（`/ws/v2/agent`）建立后立即进入 inbound receive loop。Runtime status 先恢复，settings、terminal、tunnel、process 与 run ledger 延迟 200ms 后在可中止后台任务中低优先级 replay，并在批次间 yield。 |
-| 启动空窗消除 | WebView 在 Tauri listener 异步注册完成前就先 heartbeat + drain 一次；native wake、request-ready 与 Gateway online 事件都会继续触发 drain。 |
-
-## 本地持久化模型
-
-| 数据域 | Rust 命令/服务 | 表或文件 |
-|---|---|---|
-| Providers/System/MCP/Agents/Hooks/Cron/Remote/Memory settings | `commands/settings.rs` | `~/.liveagent/config.sqlite` 内多张 settings 表 |
-| Chat history | `commands/chat_history.rs` | `~/.liveagent/chat-history.sqlite3` 的 `chatHistory`、`chatHistorySegment`、`chatHistoryShare`、FTS |
-| Memory | `services/memory.rs` | `~/.liveagent/memory/**/*.md` + `memory-index.sqlite3` |
-| Skills | `services/skills.rs` | `~/.liveagent/skills` |
-| Cron logs | `commands/settings.rs`、`services/cron.rs` | `cron_execution_logs` |
-| Subagent identity/run/message | `commands/history/subagent_store.rs` | chat history 库内 `subagentMeta` 版本标记 + `subagentIdentity`/`subagentRun`/`subagentRunSegment`/`subagentMessage`（schema v2，版本不符即 drop-and-recreate，无 event 表） |
-
-## GUI 的设计取舍
-
-| 取舍 | 原因 |
-|---|---|
-| ChatPage 仍是总编排层 | 对话运行时跨模型、工具、历史、压缩、记忆、Gateway、上传和 UI 状态，保留一个编排中心能减少跨模块隐式状态。 |
-| 高权限能力放 Rust | 文件系统、Shell、MCP 进程、SQLite、Gateway 连接、Cron 更适合在 Tauri 后端做权限与生命周期控制。 |
-| GUI 与 WebUI 复制部分 UI | 两端运行环境不同，WebUI 不能直接调用 Tauri，但需要维持体验 parity，因此复制 settings/hub/chat 组件并接入 shims。 |
-| Settings 按域保存 | provider secret、remote、cron、memory 等域有不同验证和同步策略，分域保存便于限制泄露与减少误覆盖。 |
-| Gateway 控制面优先 | 远程首条 Chat command 与 Ping/Pong 必须先于大体积状态 reconciliation；后台 snapshot replay 只负责最终一致性，不阻塞 inbound。 |

 # LiveAgent 总体架构
 
-## 系统分层
+## 一句话
 
-| 层级 | 主要路径 | 技术栈 | 核心职责 |
-|---|---|---|---|
-| 桌面 GUI | `crates/agent-gui/src` | React、TypeScript、Vite、Tailwind | Chat shell、Settings、Skills Hub、MCP Hub、Memory UI、历史侧边栏、上传与流式渲染。 |
-| 桌面后端 | `crates/agent-gui/src-tauri/src` | Tauri 2、Rust、SQLite、tokio | 系统命令、文件/Shell/进程、MCP runtime、MemoryStore、CronManager、GatewayController、代理服务。 |
-| Agent 运行时 | `crates/agent-gui/src/lib/chat`、`crates/agent-gui/src/pages/chat`、`crates/agent-gui/src/lib/tools` | TypeScript、`@mariozechner/pi-ai` | 构造上下文、请求模型、执行工具、压缩上下文、持久化历史、发布 Gateway 事件。 |
-| Gateway | `crates/agent-gateway` | Go、net/http、WebSocket+Protobuf（v2） | 桌面 Agent 与浏览器 WebUI 的远程中继、认证、会话管理、恢复缓冲、静态 WebUI 和分享页。 |
-| WebUI | `crates/agent-gateway/web` | React、TypeScript、Vite、WebSocket | 远程浏览器端 Chat/Settings/Hub 壳层，通过 Gateway 操作本地 Agent。 |
-| 资料与策略 | `doc/`、`docs/` | Markdown、SQL | 历史设计、专项计划、当前架构索引。 |
+一个 **Rust 后端** 持有全部本地能力和唯一的网络入口，一个 **Node 引擎** 跑对话循环，
+一份 **前端代码** 通过 HTTP + WebSocket 连上去——不管它跑在 Tauri 桌面壳里还是浏览器里。
+
+「本地」和「远程」不再是两条代码路径，只是端点地址不同。
 
-## 进程边界
+## 三层结构
 
-| 进程/运行环境 | 入口 | 和谁通信 | 权限边界 |
+| 层 | 路径 | 技术栈 | 职责 |
 |---|---|---|---|
-| Tauri WebView | `crates/agent-gui/src/main.tsx`、`src/App.tsx` | Tauri invoke、Gateway bridge、模型 API | 用户可见桌面界面，触发本地能力但不直接访问 Rust 内部状态。 |
-| Tauri Rust 进程 | `src-tauri/src/main.rs`、`src-tauri/src/lib.rs` | 前端 invoke、SQLite、OS、Gateway WebSocket v2、MCP server | 本地高权限真相源，负责系统能力、持久化与远程桥接。 |
-| Gateway Go 进程 | `crates/agent-gateway/cmd/gateway/main.go` | Desktop/Browser WebSocket v2（Protobuf 帧）、HTTP | 网络中继层，不直接执行本地工具。 |
-| Browser WebUI | `crates/agent-gateway/web/src/main.tsx`、`web/src/App.tsx` | Gateway `/ws/v2`、`/api/*` | 远程 UI，仅持有 token、脱敏设置和本地浏览器缓存。 |
+| 前端 | `crates/frontend/src` | React、TypeScript、Vite、Tailwind | Chat、Settings、Skills/MCP Hub、Memory、终端、Git、历史。**只经网络与后端通信。** |
+| 桌面壳（可选） | `crates/frontend/src-tauri` | Tauri 2、Rust | 托盘、窗口、自更新、原生对话框、剪贴板；并在进程内启动后端。19 个壳专属 command。 |
+| Rust 后端 | `crates/backend` | axum、tokio、rusqlite | 唯一对外网络入口（HTTP + WS）、认证；fs/shell/git/terminal PTY/sftp/sqlite/cron/mcp/memory/tunnel 的实现。 |
+| Node 引擎 | `crates/core` | TypeScript、`@earendil-works/pi-agent-core`、`pi-ai` | 对话循环：上下文构造、模型流式、工具执行、压缩、记忆抽取、历史落库。**只监听 loopback。** |
+
+浏览器形态下「桌面壳」这一层不存在，其余三层不变——这正是决策 16 要的效果。

-## 核心数据流
+**一套 API，两类客户端。** 前端和 Node 引擎打的是同一批路由、调的是 `backend`
+里同一批函数，所以工具行为不可能两边不一致——这是取消 Go 中继的直接收益。
 
-| 数据流 | 步骤 | 关键路径 |
+## 两种运行形态
+
+| | 桌面壳内嵌 | 独立后端 |
 |---|---|---|
-| 本地桌面对话 | GUI composer 提交消息，`ChatPage` 构造上下文，按 execution mode 进入 text 或 agent turn，模型流式返回，必要时执行 builtin tools，最后写入历史 SQLite。 | `src/pages/ChatPage.tsx`、`src/pages/chat/runTextConversationTurn.ts`、`src/pages/chat/runAgentConversationTurn.ts`、`src/lib/providers/llm.ts`、`src/lib/tools/builtinRegistry.ts` |
-| WebUI 远程对话 | WebUI optimistic echo 后先经 `/ws/v2` 发 `chat_prepare`，Gateway 通过关联原生 Ping/Pong 验证桌面端信封流并唤醒桌面 Chat Runtime；随后 `chat_command`（`chat.submit`/`chat.edit_resend`）accepted 并经 `/ws/v2/agent` 信封流下发。桌面端本地运行并持续回传 `ChatEvent`/`ChatControlEvent`，Gateway 按 seq 经会话订阅（`chat.subscribe`/`chat.event`）推送给 WebUI。 | `web/src/lib/gatewaySocket.ts`、`internal/protocol/pbws/browser_local.go`、`internal/chatcmd/chatcmd.go`、`proto/v2/gateway.proto`、`src-tauri/src/services/gateway/*` |
-| 设置同步 | GUI load/save 设置到本地 SQLite，同时发布脱敏 settings snapshot 到 Gateway；WebUI 读取/更新 settings 时走 Gateway，普通 sync 不带真实 provider API key。 | `src/lib/settings/*`、`src-tauri/src/commands/settings.rs`、`src/lib/settings/sync.ts`、`web/src/lib/settings/sync.ts` |
-| 历史同步 | GUI 持久化 `chatHistory` 和 `chatHistorySegment`，操作后发布 history sync；Gateway 转发给 WebUI，WebUI 刷新列表或详情缓存。 | `src-tauri/src/commands/chat_history.rs`、`src-tauri/src/services/gateway.rs`、`web/src/lib/historySync.ts` |
-| 上传文件 | GUI 直接通过 Tauri 导入；WebUI 走 Gateway HTTP multipart，Gateway 将 bytes 转成 `UploadReadableFilesRequest` 信封。桌面端统一把文件写入 `~/.liveagent/uploads` 暂存区（工作区外）后返回文件引用。 | `src-tauri/src/commands/system.rs`、`internal/handler/upload.go`、`web/src/lib/uploadReadableFiles.ts` |
-| 记忆召回 | 每轮 Chat 可调用 Rust `MemoryStore` 生成 overview 注入 system prompt；工具层暴露 `MemoryManager` 读写；Settings Memory 展示和管理同一套 store。 | `src-tauri/src/services/memory.rs`、`src/lib/chat/memory/*`、`src/lib/tools/memoryTools.ts`、`src/pages/settings/MemoryPanel.tsx` |
+| 后端从哪来 | Tauri `.setup()` 里 `start_backend_server()` 起在同进程（`src-tauri/src/backend_server.rs`） | `backend --port 8443 --engine-bundle <path>` |
+| 监听地址 | `127.0.0.1:<系统分配的空闲端口>` | `0.0.0.0:<--port>` |
+| 密码 | 每次启动随机生成，前端经 `get_backend_endpoint` 拿到 | `--password`，不给则随机生成并打到 stderr |
+| 登录页 | 跳过（壳注入端点） | 浏览器输入 host/port/密码，或用 `?backendHost=&backendPort=&token=` 链接 |
+| 退出 | 壳退出即带走后端与 Node 子进程（决策 11） | SIGTERM/SIGINT → kill Node child |
 
-## 当前主要持久化
+两者**不能同机并跑**：它们共用同一个 `~/.liveagent` 数据目录。
 
-| 数据 | 位置 | 所有者 | 说明 |
-|---|---|---|---|
-| 应用设置 | `~/.liveagent/config.sqlite` | Tauri Rust | provider/system/mcp/agents/hooks/cron/remote/memory settings。 |
-| Chat 历史 | `~/.liveagent/chat-history.sqlite3` | Tauri Rust | 对话 header、segment、share、FTS 索引。 |
-| Memory 文件 | `~/.liveagent/memory/...` | Tauri Rust | Markdown 是记忆事实源，按 global/project/daily 等目录组织。 |
-| Memory 索引 | `~/.liveagent/memory/memory-index.sqlite3` | Tauri Rust | `memory_meta`、`memory_fts`、`memory_fts_tri`、audit log。 |
-| Skills root | `~/.liveagent/skills` | Tauri Rust + GUI | 用户可安装/创建/打包的 Skills runtime root。 |
-| WebUI 本地缓存 | Browser localStorage | WebUI | token、脱敏 settings snapshot、UI 偏好与运行态辅助缓存。 |
+## 前端如何区分宿主
+
+前端只有一份代码，靠**运行时探测**降级，不靠构建分叉：
+
+| 判定 | 位置 | 用途 |
+|---|---|---|
+| `isDesktopShell()` | `src/lib/backend/endpoint.ts` | 真 Tauri internals 在场且不是我们自己装的网络 shim |
+| `hasTray/hasUpdater/hasWindowControls/…` | `src/lib/shell/capabilities.ts` | 七个语义化包装，当前全部等价于 `isDesktopShell()` |
+| `isShellCommand(cmd)` | `src/lib/backend/commandRouting.ts` | **反向白名单**：只有 19 个壳专属 command 走 IPC，其余一律走网络 |
+| `isShellEvent(event)` | 同上 | 壳自己 emit 的事件（`app:action`、`tauri://*`…）走 IPC，其余走 WS |
+
+业务代码继续写 `invoke("git_status", …)` / `listen("terminal:event", …)`——
+`lib/backend/tauriCore.ts` 与 `tauriEvent.ts` 经 vite alias 顶替真插件，
+在这一层完成分流。新增后端 command 不需要改任何名单。
+
+浏览器里缺的能力：托盘/更新/全局快捷键/窗口置顶**隐藏入口**；剪贴板降级到
+`navigator.clipboard`、外链降级到 `window.open`、上传降级到 `<input type=file>`；
+**原生"浏览…"对话框故意不降级**——它选的是后端机器上的路径，浏览器对话框选的是
+用户本机路径，语义不同，改成隐藏按钮 + 手输路径。
 
-Gateway 的 Chat relay state 不属于持久化数据：conversation event window 默认保留最近 10 分钟并受 4096 条/约 8 MiB 硬上限约束，`client_request_id` 幂等记录在当前进程保留 24 小时。Gateway 重启后由桌面历史 snapshot、run ledger 与 RuntimeStatus 重新对账。
+## Rust 后端内部
+
+| 模块 | 文件 | 说明 |
+|---|---|---|
+| 路由装配 | `backend/src/lib.rs` | `build_router()` 挂 `/healthz`（免认证）+ `/api/*`（Bearer）+ permissive CORS |
+| 命令路由 | `routes.rs` + `routes_gen.rs` | 176 条由 `scripts/generate-routes.mjs` 从 `src-tauri/src/tauri_commands/*.rs` 生成；`make check-routes` 防漂移 |
+| 状态装配 | `lib.rs::build_state()` | 建库、装 registry、把 EventBus 接到 WS sink 与各子系统 |
+| 事件流 | `ws.rs` | EventBus → `broadcast`(256) → 每连接一个 pump；队列满丢最旧帧，不阻塞业务线程 |
+| 认证 | `auth.rs` | 密码即 Bearer token（决策 7）；另有内部 token 区分 Node 调用方 |
+| 引擎代理 | `engine_proxy.rs` | `chat_send`/`chat_abort`/`conversation_live` 反代到 Node；`engine_emit_event` 收事件回流 |
+| 引擎守护 | `engine_process.rs` | spawn Node、`/healthz` 就绪探测、崩溃后指数退避重启（上限 30s） |
+| 工具审批 | `approval.rs` | Node 发起、前端应答的反向往返（见 protocols.md） |
+| 出网防护 | `ssrf.rs` | IP 黑名单，含 NAT64/6to4 内嵌 IPv4 递归检查 |
+| TLS | `tls.rs` | `--tls-cert` / `--tls-key`，内建与反代都支持（决策 14） |
+
+能力实现在 `crates/backend`：`commands/`（automation / config / history /
+integration / runtime / workspace）、`services/`（automation / memory / skills /
+tunnel / workspace_watch / provider_models / provider_usage / system_proxy /
+power_activity）、`runtime/`（terminal / sftp / shell_runner /
+managed_process / process / task_runner / project_path / platform）。
+
+**`backend` 的 `Cargo.toml` 禁止依赖 tauri**（决策 2）。这是编译期防线：
+后端要能在没有窗口系统的容器里跑，靠人自觉守不住。
+
+## Node 引擎内部
+
+`src/index.ts` 只做认证、路由、JSON 编解码，业务全在 `engine.ts`：
+
+- `acceptChatSend()` **同步**去重 + 入队后立即返回 202，turn 在队列里异步跑。
+  增量与终态全走事件广播，不在 HTTP 响应里。
+- 并发模型：多会话 async 并发，**同会话内一条 Promise 链串行**。
+- `getConversationLiveSnapshot()` 的快照源是**引擎内存态**，不是 SQLite——
+  `runAgentConversationTurn` 只在函数末尾落一次库，turn 中读库读不到半条消息。
+- 工具执行、设置读取、历史落库全部经 `backendClient.ts` 的 `callBackend()`
+  打回 Rust，走的是前端用的同一批路由。
+
+## 持久化
+
+| 数据 | 位置 | 所有者 |
+|---|---|---|
+| 应用设置 | `~/.liveagent/config.sqlite` | Rust 后端 |
+| Chat 历史 | `~/.liveagent/chat-history.sqlite3` | Rust 后端（`initialize_history_db()` 在 `build_state` 第一步） |
+| Memory 事实 | `~/.liveagent/memory/**/*.md` | Rust 后端；Markdown 是事实源 |
+| Memory 索引 | `~/.liveagent/memory/memory-index.sqlite3` | Rust 后端 |
+| Skills | `~/.liveagent/skills` | Rust 后端 |
+| 上传暂存 | `~/.liveagent/uploads/<batch>/` | Rust 后端 |
+| 端点与 UI 偏好 | 浏览器 localStorage | 前端（壳内不用，端点由壳注入） |
+
+**这些全在后端所在的机器上。** 桌面壳形态下后端就在本机，与旧版一致；
+独立部署时它们在服务器上——密钥也在那里。定位从「本地优先」改成
+「后端由你自己部署」。
 
 ## 设计原则
 
-| 原则 | 在当前代码中的体现 |
+| 原则 | 体现 |
 |---|---|
-| 桌面端是真相源 | 工具执行、历史、设置、记忆、Cron prompt、MCP runtime 都在 Tauri/GUI 侧落地。 |
-| Gateway 不越权 | Gateway 不直接访问用户文件系统，不保存真实 provider key；只维护会话、中继和有界的进程内 Chat 事件窗口。 |
-| GUI/WebUI 可用性对齐 | WebUI 复制/镜像了大量 GUI 组件与 settings 子树，但用 shims 和 Gateway client 替换 Tauri API。 |
-| 长对话可恢复 | 历史使用桌面端 segment + summary checkpoint；短时断线由 Gateway 内存 seq window 和 `chat.subscribe.after_seq` 补齐，窗口 reset 或 Gateway 重启时回到桌面历史 snapshot。 |
-| 功能域清晰 | Chat runtime、Tools、Memory、Skills、MCP、Cron、Hooks、History 都有独立源码区域与后端命令。 |
+| 唯一网络入口 | 认证、TLS、SQLite 全在 Rust；Node 只监听 loopback，前端够不着（决策 5） |
+| 一套 API 两类客户端 | 前端与 Node 引擎共用 `/api/<command>`，行为不可能分叉 |
+| 一份前端代码 | 壳能力运行时探测降级，不做构建分叉（决策 16） |
+| 前端不在场不阻塞 | 引擎跑在后端，前端只是渲染；该超时超时，有推荐项自动选（决策 10） |
+| 重连不补发 | 拉快照 + 订阅增量；没有 `seq`/`after_seq`/replay buffer（决策 19） |
+| 编译期防线优于约定 | `backend` 禁 tauri 依赖，CI 另有 `cargo tree` 门禁 |

-# 协议与同步合同
+# 协议：JSON over HTTP + WS
 
-## 协议总览
+自 v2 起，线上协议只有一种：**JSON**。protobuf、buf 工具链、`proto/v2` 全部删除
+（决策 6）。契约不再需要代码生成，也就不再有生成物漂移门禁。
 
-自 v2 起，网关的全部实时链路统一为 **WebSocket + Protobuf**（下称 v2 协议）。
+权威定义就是代码本身：`crates/backend/src/routes.rs`（响应形状）、
+`routes_gen.rs`（命令路由，由 `scripts/generate-routes.mjs` 生成）、
+`ws.rs`（事件帧）、`engine_proxy.rs`（引擎代理与事件回流）。
 
-| 通道 | 端点 | 方向 | 用途 |
-|---|---|---|---|
-| **v2** WebSocket | `GET /ws/v2` | WebUI <-> Gateway | 浏览器主链路：本地操作 + `GatewayEnvelope` 直通请求 + 广播事件。 |
-| **v2** WebSocket | `GET /ws/v2/agent` | Desktop <-> Gateway | 桌面端常驻双向信封流。 |
-| **v2** WebSocket | `GET /ws/v2/terminal` | 两端 <-> Gateway | 终端专用数据面（角色由 hello 区分），承载 `TerminalStreamFrame`，避免终端 IO 与 chat/settings/history 队头阻塞。 |
-| HTTP API | `/api/status` | WebUI -> Gateway | Agent 在线状态 + `protocol_usage`（v2 使用计数）。 |
-| HTTP upload | `/api/files/import` | WebUI -> Gateway -> Desktop | 上传可读文件并导入桌面 workspace。 |
-| Public HTTP | `/api/public/history-shares/{token}` | Browser -> Gateway | 公开只读历史分享。 |
-
-## v2 统一线协议
-
-权威定义：`crates/agent-gateway/proto/v2/gateway_ws.proto`（帧壳），业务消息
-全部复用 `proto/v2/gateway.proto`（`GatewayEnvelope`/`AgentEnvelope`/
-`TerminalStreamFrame` 等——单一事实源，三端 Go/Rust/TS 均由它生成）。
-
-### 传输与握手
-
-- WebSocket 子协议：`liveagent.v2.pb`（服务端必回显）。
-- 一条 WS 二进制消息 = 一条 proto 帧消息，无长度前缀；v2 路径上文本帧被忽略。
-- 首帧必须为 `ClientHello{protocol_version=2, role, token, ...}`；服务端应答
-  `ServerHello{ok, session_id, heartbeat_period_seconds, max_message_bytes}`；
-  鉴权失败以 close code 4401 关闭。agent 角色的 hello 同时完成会话登记。
-- 消息大小上限按链路收紧并经 `ServerHello.max_message_bytes` 通告：`/ws/v2`
-  浏览器 4 MiB、`/ws/v2/agent` 沿用 `MaxMessageBytes`（默认 64 MiB，上传
-  需要）、`/ws/v2/terminal` 浏览器 1 MiB / Agent 16 MiB。并发连接上限
-  agent 256 / browser 128 / terminal 512（超限升级前 503）；浏览器链路另有
-  每连接在途派发上限 16 与入站令牌桶 100 帧/s（burst 200）。
-
-### 浏览器链路（/ws/v2）
-
-- 请求帧 `WebClientFrame{request_id, agent_id, oneof payload}`；响应帧回显同一
-  `request_id`；广播帧 `request_id` 为空。
-- **多 Agent 寻址**：目标型请求必须显式携带非空 `agent_id`，缺失时收到
-  `local_error: "agent_id is required"`。官方 WebUI 首次连接会先请求
-  `agent_list`，自动选择一个在线 Agent 并持久化选择，因此单 Agent 部署无需
-  手工操作；广播帧的 `agent_id` 标注事件来源，客户端严格过滤非活跃 Agent。
-  `agent_list` 返回全部已登记 Agent 的状态目录（含离线与仅签发凭证的条目）。
-- **直通请求** `agent_request`（浏览器直接构造 `GatewayEnvelope` 载荷臂）：
-  网关按白名单与限额校验（`internal/protocol/pbws/guard.go`；功能门控按目标 Agent 的 settings 快照判定）、把
-  `request_id` 按连接命名空间化后近乎原样转发目标桌面端，
-  响应以原始 `AgentEnvelope`（`agent_response` 臂）回送。原先约 90 个
-  “JSON 解码 → 手工组 proto → 手工拆 map” 处理器由这一条路径取代。
-- **本地帧**（网关状态直接应答/编排）：`status_get`、`chat_prepare`、
-  `chat_command`（携带 `ChatCommandRequest`）、`chat_subscribe`/
-  `chat_unsubscribe`/`chat_activities`、`workspace_subscribe`/`workspace_unsubscribe`。 其中 `chat.subscribe` 与 `chat.unsubscribe` 同样属于目标型操作，必须携带非空 `agent_id`；会话流按 `(agent_id, conversation_id)` 隔离，`chat.activities` 是全局目录查询。
-- **广播臂**：`history_event`/`settings_event`/`terminal_event`/`sftp_event`/
-  `chat_queue_event`/`tunnel_state`/`process_state`/`workspace_activity`
-  直转 session 层的 seam 消息；`status`/`chat_activity`/`chat_event`/
-  `chat_command_update`/`chat_subscription_reset` 为 proto 化载荷。
-  chat 事件载荷保持动态 JSON（`payload_json` bytes）。
-- **本地错误**：`local_error`（`ErrorResponse`）。
-- 心跳与背压：服务端 WS 控制帧 ping + 应用层 `PingFrame` 双通道；空闲驱逐
-  `3×心跳周期+宽限`；写侧为控制优先双队列 + 可掉帧数据 + 关联响应掉帧即
-  断连（`internal/transport/wscore` 连接运行时）。
-
-### 桌面端链路（/ws/v2/agent）
-
-hello（role=AGENT）完成鉴权与会话登记后进入双向信封流：网关下行
-`GatewayEnvelope`（请求 + 周期 Ping），桌面端上行 `AgentEnvelope`
-（响应/事件/Pong）；心跳走独立通道不受数据拥塞影响；传输层保活由 WS 控制帧
-ping/pong 承担，客户端以 3×心跳周期无入站为断链判据。
-
-**多 Agent**：网关按 `agent_id` 维护多个并存的 Agent 会话（≤10 台规模），
-同 `agent_id` 重连只顶掉该 id 的旧连接，不同 Agent 互不影响。快照
-（settings/终端/提示队列/托管进程）与广播事件按 Agent 隔离，隧道帧拒绝
-跨 Agent 的 stream_id 伪造。每个桌面端首次初始化设置时自动生成并持久化规范的
-`agent-UUIDv4`；设置页只读展示该标识，不依赖 hostname 或用户手工命名。
-
-### Agent 鉴权（每 Agent 独立凭证）
-
-网关默认自动创建内嵌 SQLite 数据库（可用 `-agent-db` 或
-`LIVEAGENT_GATEWAY_AGENT_DB` 指定路径）并启用每 Agent 凭证存储：
-
-- Agent 链路接受网关 Token 或按 `agent_id` 签发的独立凭证（`agt_` 前缀）；
-- Agent 独立凭证只授权绑定的 Agent 链路，不能冒充浏览器或调用 REST；网关 Token
-  同时授权浏览器、管理 API 和 Agent 链路；
-- 凭证可持续用于对应 Agent 连接，但明文只在签发响应展示一次，落盘仅存
-  SHA-256（SQLite 文件权限 0600）；
-- 管理 API（管理 token 门禁）：`GET /api/agents` 目录、
-  `POST /api/agents/{id}/token` 签发/轮换并设置可选名称；轮换会立即断开当前 Agent
-  会话、使旧凭证无法重连、
-  `PATCH /api/agents/{id}` 修改或清空名称、`DELETE /api/agents/{id}` 删除整条记录、
-  凭证并即时断开该 Agent 的活跃会话。
-
-Gateway 数据库的首版 Agent 结构为单表 `agents`。`agent_id` 主键服务凭证点查、
-名称更新和删除；`(created_at, agent_id)` 组合索引服务数据库层目录分页。
-
-网关 Token 与独立 Agent 凭证可以并存：使用网关 Token 的客户端必须提供稳定的
-`agent_id`，使用独立凭证的客户端还会受到 `agent_id` 绑定校验。
-
-### 终端链路（/ws/v2/terminal）
-
-两端共用一条路径，hello.role 区分浏览器/桌面端；hello 之后双向承载
-`TerminalStreamFrame`（proto 直传）。浏览器角色以 `hello.agent_id` 绑定数据面的
-目标 Agent；`agent_id` 必填，出站按绑定路由、入站只放行同源帧。
-attach/detach 维护本连接订阅集，input/resize 需已附着，output 只投递给
-已附着连接；桌面端侧就绪信号由 `ServerHello` 承担。

-## Chat 协议
+## 端点总览
 
-| 阶段 | WebUI -> Gateway | Gateway -> Desktop | Desktop -> Gateway -> WebUI |
+| 端点 | 方法 | 认证 | 用途 |
 |---|---|---|---|
-| 唤醒 | `chat_prepare` | `PingRequest{request_id=chat-runtime-wake-*}` | Rust emit WebView wake，可靠返回关联 `PongResponse`；Gateway 完成真实原生往返后响应当前 status。 |
-| 提交 | `chat_command`，`type=chat.submit` | `ChatCommandRequest{type=chat.submit}` | `chat_accepted` 携带 `run_id`/`accepted_seq`；用户消息与 token 事件经会话订阅 `chat_event` 推送。 |
-| 编辑重发 | `chat_command`，`type=chat.edit_resend` | `ChatCommandRequest{type=chat.edit_resend, base_message_ref}` | Gateway 先发布 `rebased` 与新用户消息事件，桌面端随后原子截断并运行新 turn。 |
-| 恢复 | `chat_subscribe`，`{conversation_id, after_seq, stream_epoch}` | 无 | WebUI 先用 history snapshot/projection hydrate，订阅响应由 Gateway 进程内事件窗口按 conversation seq 跨 run 补发缺失事件（`events_json`/`latest_seq`/`reset`）；epoch 改变或窗口不足时返回 reset。订阅缓冲溢出时 Gateway 发 `chat_subscription_reset`，客户端按游标重新订阅。 |
-| 取消 | `chat_command`，`type=chat.cancel` | `ChatCommandRequest{type=chat.cancel}` | Gateway 置 `cancelling` 状态，桌面端真实终态优先，超时由 watchdog 兜底 `run_finished(cancelled)`。 |
-| 完成 | 无 | 无 | `ChatEvent.type=DONE` 映射为 `run.completed` 终态。 |
-
-桌面端仍通过 `ChatEvent` 表达 `TOKEN`、`THINKING`、`TOOL_CALL`、`TOOL_RESULT`、`DONE`、`ERROR`、`TOOL_STATUS`、`HOSTED_SEARCH` 等低层事件。Gateway 对外统一附加同 conversation 内单调递增的 `seq`，并把控制事件规范化为 `run.accepted`、`user.message.appended`、`conversation.rebased`、`projection.updated`、`run.completed`、`run.failed`、`run.cancelled` 等 WebUI 事件。命令编排逻辑（去重、探活、接受回执、启动看门狗）收敛于 `internal/chatcmd`。
+| `/healthz` | GET | **无** | 探活。只回 `ok`，不泄露任何信息 |
+| `/api/<command>` | POST | Bearer | 176 条命令路由，1:1 对应 `#[tauri::command]` |
+| `/api/events` | GET（WS） | `?token=` | 事件流，单向下行 |
+| `/api/chat_send` | POST | Bearer | 反代到 Node 引擎 |
+| `/api/chat_abort` | POST | Bearer | 反代到 Node 引擎 |
+| `/api/conversation_live` | GET | Bearer | 反代到 Node 引擎，取内存快照 |
+| `/api/tool_approval_request` | POST | Bearer | Node 发起审批，长挂起 |
+| `/api/tool_approval_respond` | POST | Bearer | 前端应答审批 |
+| `/api/engine_emit_event` | POST | **仅**内部 token | 引擎事件回流到 EventBus |
 
-WebUI 对 command ACK 使用 4 秒上限。连接中断或 ACK 丢失时仅重试一次，并复用完全相同的 payload 与 `client_request_id`；Gateway 在同一进程内原子返回 canonical run，因此不会重复 seed 或 dispatch。成功 prepare 的探测新鲜度绑定 Agent session epoch 并保留 2 秒，紧随 command 可直接复用，避免正常路径重复原生 RTT；`chat_accepted` 与 `chat_prepare` 响应走 WebSocket 控制优先队列，避免被 token 数据帧队头阻塞。
+`/healthz` 故意放在认证之外——探活要密码的话容器编排拿不到健康状态。
 
-## Settings 同步
+## 认证
 
-| 操作 | 方向 | 语义 |
-|---|---|---|
-| `SettingsGetRequest`（直通） | WebUI -> Gateway -> Desktop | 读取桌面端当前 settings snapshot。 |
-| `SettingsUpdateRequest`（直通） | WebUI -> Gateway -> Desktop | 更新设置；provider secret 使用单独 `providerApiKeyUpdates`。 |
-| `settings_event` / `SettingsSyncEvent` | Desktop -> Gateway -> WebUI | GUI 本地保存后广播脱敏 settings snapshot（`settings_json` 由客户端解析）。 |
+密码**直接**当 Bearer token（决策 7）。没有 JWT、没有 session，整个系统一把钥匙。
 
-设置协议的关键约束是 provider API key 不走普通 sync snapshot。WebUI 只能看到 redacted provider 数据和 `apiKeyConfigured` 状态。
+```http
+POST /api/git_status HTTP/1.1
+Authorization: Bearer <password>
+Content-Type: application/json
 
-## History 同步
+{"workdir": "/path/to/repo"}
+```
 
-| 操作 | 语义 |
+| 事项 | 约定 |
 |---|---|
-| `HistoryListRequest` | 分页读取 conversation summary，用于 sidebar；网关钳制分页（page 默认 1、page_size 默认 80 上限 200）。 |
-| `HistoryGetRequest` | 读取 conversation detail；支持 `max_messages` 返回 tail window。 |
-| `HistoryRenameRequest` | 修改标题并广播 upsert event。 |
-| `HistoryPinRequest` | 修改置顶状态并保持排序。 |
-| `HistoryShareGet/SetRequest` | 管理公开分享 token 与 redaction 选项。 |
-| `HistoryDeleteRequest` | 删除会话和相关 FTS/share 行。 |
-| 编辑重发截断 | 不再暴露独立 WebUI history 命令；由 `chat.edit_resend` 在桌面端处理，并通过 `conversation.rebased`/`projection.updated` 同步视图。 |
+| 比较方式 | 常量时间（`subtle::ConstantTimeEq`）；长度不等时跟自己比，耗时只取决于存储值长度 |
+| 失败响应 | 缺 header、格式错、密码错**都是同一个 401**，不区分 |
+| scheme | `Bearer` 大小写不敏感 |
+| 两把钥匙 | 用户密码 → `CallerIdentity::User`；内部 token → `CallerIdentity::Internal`。后者只发给 Node 引擎，`engine_emit_event` 只认它，别的身份一律 403 |
+| WebSocket | 浏览器 WebSocket API 设不了 header，所以 `/api/events` 用 `?token=` 做等价校验 |
+| CORS | permissive。认证是 Bearer 而非 cookie/同源，放开不引入新攻击面 |
 
-桌面端是历史数据库真相源；Gateway 负责 request forwarding 和 sync event broadcasting；WebUI 负责本地列表和 transcript 状态更新。
+## 命令路由：命令式，不做 REST 化
 
-## Upload 协议
+```text
+invoke("git_status", { workdir })   →   POST /api/git_status   { "workdir": "..." }
+```
 
-| 步骤 | 说明 |
+| 规则 | 说明 |
 |---|---|
-| 1 | WebUI 将文件通过 multipart POST 到 `/api/files/import`。 |
-| 2 | Gateway 读取文件 bytes，注册 request stream，转成 `UploadReadableFilesRequest` 发给 Desktop。 |
-| 3 | Desktop 把文件写入应用上传暂存区 `~/.liveagent/uploads/<batch>/`（工作区外），返回 `ChatUploadedFile` 列表和 skipped 列表。 |
-| 4 | WebUI 把返回的 uploaded files 附加到下一次 Chat Command。 |
+| 路径 | `/api/` + command 名，逐字一致 |
+| body | 参数对象，key **就是** `#[tauri::command]` 的参数名 |
+| 无参命令 | 发 `{}`，后端按无字段结构体反序列化 |
+| 成功 | `200 {"ok": <返回值>}` |
+| 业务失败 | `400 {"error": <原样序列化的错误值>}` |
+| 服务端故障 | 500 留给 panic 和序列化失败 |
 
-GUI 本地上传不需要 HTTP/Gateway，直接通过 Tauri command 导入。上传臂不在
-`agent_request` 直通白名单内（大文件走 HTTP multipart 更合适）。
+**为什么包一层 `ok`**：一部分命令返回 `()`，裸放会得到 `null`，与「真的返回了
+null」分不开。包一层让 200 永远是一个对象。
 
-## Public Share 错误码
+**为什么错误不 stringify**：多数命令的错误是 `String`，但 `fs_*` 返回结构化的
+`FsCommandError`（`code` / `path` / `didYouMean`），前端在读这些字段。转成字符串
+等于把它们扔掉。
 
-`/api/public/history-shares/{token}` 仍然通过 Gateway 转发到桌面端解析 share token。桌面端返回 `ErrorResponse.code` 后，Gateway HTTP 直接按 code 映射状态：
+**为什么只有 200/400 两档**：与 Tauri IPC 语义一致——命令返回 `Err` 就是「这次做
+不到」（路径不存在、参数不合法、不是 git 仓库），不是服务端崩了。补细 404/403
+需要逐个命令审计错误来源，收益不抵成本。
 
-| code | HTTP | 场景 |
-|---:|---:|---|
-| `400` | Bad Request | share token 为空或请求非法。 |
-| `404` | Not Found | 分享链接不存在、已关闭，或对应历史对话不存在。 |
-| 其他 | Bad Gateway | 桌面端处理失败或返回未知错误。 |
+**为什么不 REST 化**：前端现在就在用这些命令名和参数对象。1:1 映射让迁移是机械
+替换；REST 化等于做 176 次独立设计决策，每次都是一个破坏前端的机会。这是消除
+特殊情况，不是制造 176 个。
 
-Gateway 不再通过错误文案推断 public share 状态，错误语义由桌面端产生并通过 proto 传递。
+`rename_all` **逐命令**沿用 Tauri 现状，不统一：写了 `snake_case` 的用
+snake_case，没写的用 camelCase（Tauri 默认）。已知不一致的有
+`git_clone_repository_tasks`、`chat_history_replace_from_message`。统一它们就是
+破坏前端。
 
-## Terminal Stream 协议
+参数提取不用 `axum::Json`：它的提取失败是 422/415 纯文本，违反「所有失败都是
+400 + `{error}`」的契约。`crate::json::Json` 把这些折进同一形状。
 
-终端为独立 stream 模型。主链路（`/ws/v2` 直通 `TerminalRequest`）只承载
-session list/create/close/rename、SSH prompt、SSH tabs 等控制面与 metadata
-同步；高频 `attach/input/resize/output/detach` 走 `/ws/v2/terminal` 数据面。
+### 路由生成与漂移门禁
 
-| 层级 | 合同 |
+| 命令 | 作用 |
 |---|---|
-| Browser-Gateway | `GET /ws/v2/terminal` 首帧 `ClientHello{role=BROWSER}`；之后 `TerminalClientFrame{frame}` / `TerminalServerFrame{frame}` 双向承载 proto `TerminalStreamFrame`。 |
-| Frame 字段 | `kind` 为 `attach/input/resize/detach/output/snapshot/error`；含 `stream_id/session_id/project_path_key/seq/start_offset/end_offset/cols/rows/max_bytes/truncated/error/data`。 |
-| Desktop-Gateway | `GET /ws/v2/terminal` 首帧 `ClientHello{role=AGENT}`，其后承载 `TerminalStreamFrame`；主链路不承载 terminal output/input/resize。 |
-| Snapshot | attach 返回 `snapshot` frame，data 为 tail bytes，`start_offset/end_offset` 用于前端去重。 |
-| Input | input frame 为 fire-and-forget bytes；不返回 session metadata，不进入普通 request pending map。 |
-| Resize | resize frame 只发送最新 cols/rows；不返回 session metadata。 |
-| Output | output frame 只携带轻量 session id、project key、offset 与 bytes；React session state 不因 output 更新。 |
-| 页面 stream client | 每页按 token 维护一条 terminal stream，上游按 session 复用 attach；同 session 的多个 handle 共享 output。 |
+| `make update-routes` | 从 `crates/frontend/src-tauri/src/tauri_commands/*.rs` 重新生成 `routes_gen.rs` |
+| `make check-routes` | 校验一致性，漂移即失败（CI 用） |
+
+另有契约测试拿 `routes::routed_commands()` 与 backend 导出的命令清单比对：
+**新增 command 未加路由必须导致测试失败**。
 
-Gateway 的终端连接只维护本连接内的 session attach 集合；detach 只影响这条 terminal stream 的输出投递，不改变桌面端 terminal registry。
+> 「路由可达」≠「命令可用」。契约测试把 400 也算通过（空 body 反序列化失败是正常
+> 的），于是「路由挂上了但底层没初始化」能骗过它——实测抓到过漏
+> `initialize_history_db()`、漏 `TunnelStore::initialize()` 两例。所以另有一组
+> 带**真实参数**、必须 200 且带 `ok` 的用例。
 
-## Workspace Activity 协议
+## 事件流（`/api/events`）
 
-Git 面板与文件树不再轮询：桌面端 `workspace_watch` 服务（notify watcher，250ms 去抖，`.git` 内部噪声过滤，changedPaths 封顶 64 + truncated）为每个被观察的 workdir 发出失效信号。
+单向下行，客户端发来的消息一律忽略。帧格式：
 
-| 层级 | 合同 |
+```json
+{"event": "terminal:event", "payload": { ... }}
+```
+
+| 事项 | 约定 |
 |---|---|
-| Desktop 内 | Tauri 事件 `workspace:activity`，payload `{workdir, revision, fs, git, changedPaths, truncated}`；前端经 `workspace_watch_set(workdirs)` 声明式注册本 webview 的观察集合。 |
-| Desktop→Gateway | `AgentEnvelope.workspace_activity`（`WorkspaceActivityEvent`，字段 90）。Gateway→Desktop 用 `GatewayEnvelope.workspace_watch`（`WorkspaceWatchRequest`，声明式全量 workdir 集合；订阅计数变化与 agent 重连时重发）。 |
-| Browser-Gateway | `/ws/v2` 帧 `workspace_subscribe/workspace_unsubscribe {workdir}`，事件臂 `workspace_activity`。 |
-| 语义 | best-effort 失效信号，不保证不丢事件：客户端在（重）订阅、通道重建、revision 回退时必须自标脏并 refetch。revision 为 per-workdir 单调计数（agent 进程内）。 |
-| 消费端 | 两端镜像的 `lib/workspace-activity/useWorkspaceInvalidation`：面板隐藏时只置脏、激活时冲刷；数据本体仍走既有 fs/git 拉取命令（invalidate-push + fetch-on-demand）。 |
+| 传输 | 文本帧，一帧一条 JSON |
+| 队列 | 服务端 `broadcast` channel，容量 256（约 2–3 秒缓冲） |
+| 背压 | **队列满丢最旧帧**，不阻塞业务线程。慢客户端不能拖住 agent 逻辑 |
+| Lagged | 客户端错过被挤掉的帧时**继续**，不断连 |
+| 多客户端 | 一个后端支持多前端同时连（决策 9），每连接一个订阅者 |
+| 重连 | **不补发**（决策 19）。客户端自己拉快照再订阅增量 |
+
+**没有 `seq`、没有 `after_seq`、没有 replay buffer。** 这是有意的：旧 Go 中继里
+约 3,800 行代码专门在给「引擎跑在一个会睡着的浏览器标签页里」擦屁股，引擎搬到
+后端之后这些机制失去存在理由。前端重连后重新拉一次快照，比维护一套跨进程的
+事件窗口简单得多。
+
+前端侧：`src/lib/backend/transport.ts` 全局只维护**一条** WS，按事件名分发给
+订阅者；断线以 500ms 起指数退避重连、上限 10s，且全局只允许一个待触发定时器
+（订阅者有十几个，不去重的话退避链会成倍增长）。
+
+### 事件来源分流
+
+桌面壳内嵌的 `backend` 是**另一个** EventBus 实例，所以「壳发的」和
+「后端发的」两组事件名**互不相交**，按名字分流是确定的：
+
+| 来源 | 事件 | 通道 |
+|---|---|---|
+| Tauri 壳 | `app:action`、`app:action-feedback`、`terminal:exit-requested`、`global-shortcut:*`、`tauri://*` | IPC |
+| 后端 | `terminal:event`、`terminal:stream`、`sftp:event`、`tunnel:state`、`workspace:activity`、`token_delta`、`run_ended`、`tool-approval:request`、`engine:crashed` … | WS |
+
+判定在 `src/lib/backend/commandRouting.ts::isShellEvent()`。
+
+## Chat 协议
 
-## Skills 与 Memory 管理协议
+Chat 是唯一不落在 `backend` 上的能力——它在 Node 引擎里。Rust 反向代理三条
+路由，剥掉 `/api` 前缀转发到 `http://127.0.0.1:<node_port>`，并补上内部 token。
 
-| 能力 | 直通请求臂 | Desktop 落点 |
+| 步骤 | 请求 | 响应 |
 |---|---|---|
-| Skills 列表和管理 | `SkillFilesListRequest`、`SkillManageRequest`、`SkillMetadataReadRequest`、`SkillTextReadRequest` | `system_ensure_builtin_skills`、`system_manage_skill`、`system_read_skill_*`、`services/skills.rs` |
-| Memory 管理 | `MemoryManageRequest` | `commands/memory.rs`、`services/memory.rs` |
-| Cron 管理 | `CronManageRequest` | `commands/cron.rs`、`services/cron.rs`、settings cron 表 |
+| 提交 | `POST /api/chat_send` `{conversationId, text, clientRequestId?, mode?, sessionId?, workdir?, skillsEnabled?, selectedModel?, selectedSkillNames?}` | `202 {"ok": {accepted: true, duplicate?: true}}` |
+| 取消 | `POST /api/chat_abort` `{conversationId}` | `200 {"ok": {aborted: bool}}` |
+| 快照 | `GET /api/conversation_live?conversationId=…` | `200 {"ok": {conversationId, isRunning, live, messageCount}}` / `404` |
+| 引擎未起 | 任一条 | `503 {"error": "引擎未启动"}` |
+
+**受理即回 202**：增量与终态全走事件广播，不在 HTTP 响应里。`clientRequestId`
+在引擎进程内按会话去重，重复提交返回 `duplicate: true` 而不是跑第二遍。
+
+`conversation_live` 返回 404 表示**引擎内存里没有**，不等于会话不存在——可能只是
+本进程还没跑过它的 turn。前端应把 404 当作「无 live 增量」，基线走历史接口。
+快照源必须是引擎内存态：`runAgentConversationTurn` 只在函数末尾落一次库，
+turn 中读库读不到正在生成的半条消息。
+
+### Chat 事件
 
-## 恢复与去重机制
+引擎经 `POST /api/engine_emit_event {event, payload}` 把事件打回 Rust，Rust
+直接广播到 EventBus，前端从 `/api/events` 收到。载荷里的会话标识是
+`conversation_id`（下划线）。
 
-| 机制 | 位置 | 目的 |
+| 事件 | payload | 前端处置 |
 |---|---|---|
-| `clientRequestId` | WebUI Chat Command -> Gateway session manager | 进程级 24 小时幂等键；并发或单次 ACK 恢复重试返回同一 canonical run。Gateway 重启后不保留。 |
-| `conversationId` -> run index | Gateway session manager | 当前会话刷新/切换后可定位正在运行的事件流。 |
-| `Seq` | Gateway 进程内 conversation event window / `chat_event` payload | 同 conversation 内单调递增；断线后 `chat_subscribe` 携带 `after_seq` 游标补发窗口内缺失事件，窗口不足时 reset + history hydrate。 |
-| 直通关联 id 命名空间 | Gateway v2 relay | 多标签页共享一个桌面端；网关按连接为 `request_id` 加前缀转发、回程剥离，杜绝跨连接冲突。 |
-| done retention | Gateway session manager | 已结束 run 短时间保留，支持刷新后看到终态。 |
-| local running ids | WebUI App | 避免正在运行会话被错误切换或误删。 |
+| `token_delta` | `{conversation_id, delta}` | 追加到草稿助手文本 |
+| `tool_status_change` | `{conversation_id, status, isCompaction, retryAttempts}` | 更新工具状态行 |
+| `chat:run-event` | `{conversation_id, ...event}` | 其余 wire 事件原样打包（工具调用/结果/思考/检查点等） |
+| `chat:compaction-status` | `{conversation_id, status}` | 压缩进度 |
+| `chat:hook-warning` | `{conversation_id, warning}` | hook 告警 |

+| `engine:crashed` | `{timestamp_ms, reason}` | Node 进程退出，Rust 守护发出 |
+
+### 工具审批：唯一的反向往返
+
+引擎搬到后端后，后端要**主动**向前端发起请求并等回答，而前端可能没连着。
+这是全系统唯一一处后端等前端的地方：
+
+```text
+Node 引擎                Rust 后端                    前端
+   │                        │                           │
+   │ POST /api/tool_approval_request                    │
+   │  {conversation_id, tool_call_id, tool_name,        │
+   │   summary, recommended?, timeout_ms?}              │
+   ├───────────────────────►│                           │
+   │                        │ emit "tool-approval:request"
+   │                        │  {approval_id, ..., timeout_ms}
+   │                        ├──────── WS ──────────────►│
+   │                        │                           │ 用户点击
+   │                        │  POST /api/tool_approval_respond
+   │                        │◄──────────────────────────┤
+   │                        │   {approval_id, decision}  │
+   │◄───────────────────────┤                           │
+   │  200 {"ok": {decision}} │                          │
+```
+
+| 事项 | 约定 |
+|---|---|
+| `decision` | `approve` / `deny` / `approve_session` |
+| 挂起时长 | Node 传 `timeout_ms`，缺省兜底 60s。**超时权威在后端** |
+| 倒计时 | `timeout_ms` 一并广播给前端，前端用它算倒计时，不自设窗口 |
+| 前端不在场 | 按决策 10，超时即按 `recommended` 或默认决策走，不阻塞主流程 |
+| 重复应答 | `409 {"error": "AlreadyAnswered"}`——这是 200/400 之外唯一的例外状态码 |
+| 无效 decision | 400 |
+
+## Rust ⇄ Node
+
+Node 只监听 `127.0.0.1`，端口由 Rust 在启动时 `bind :0` 选定并经环境变量注入。
+
+| 变量 | 含义 |
+|---|---|
+| `LIVEAGENT_NODE_PORT` | Node 自己监听的端口 |
+| `LIVEAGENT_BACKEND_PORT` | Rust 后端端口，Node 回调用 |
+| `LIVEAGENT_INTERNAL_TOKEN` | 双向认证的内部 token |
+
+Node 打回 Rust 走的是**同一套** `/api/<command>`（决策 13），只是 Bearer 换成内部
+token（`src/backendClient.ts`）。所以引擎执行 `fs_read_text` 和前端点开文件树
+执行 `fs_read_text` 是同一个函数、同一套参数、同一种错误。
+
+进程守护（`engine_process.rs`）：spawn → `GET /healthz` 就绪探测（30s 上限）→
+通过后才写 `node_port` 状态。Node 退出时广播 `engine:crashed`，指数退避重启
+（1s 起，上限 30s，连续健康 60s 后重置），**重启后端口会变**。按决策 5 不自动
+重跑对话，只标记失败和广播终态。
+
+## TLS 与部署形态
+
+| 形态 | 配置 |
+|---|---|
+| 内建 TLS | `--tls-cert <pem> --tls-key <pem>`，走 `axum_server::bind_rustls` |
+| 反代 | 不给证书参数，明文监听，由 nginx/Caddy/平台终结 TLS |
+| 桌面壳内嵌 | 明文，只监听 `127.0.0.1` |
+
+两种都支持（决策 14）。浏览器端 `secure` 标志决定用 `https`/`wss` 还是
+`http`/`ws`，默认跟随页面协议。
 
 ## 协议改造注意点
 
 | 场景 | 必查点 |
 |---|---|
-| 新增 Gateway request | 在 `proto/v2/gateway.proto` 加请求/响应臂（编号只增不改）→ `buf generate` → v2 直通白名单（`internal/protocol/pbws/guard.go`）放行 → WebUI client method + adapter；桌面端 `envelope_handler.rs` 增加分支。不再需要 Go 手工 payload 塑形。 |
-| 新增本地/编排操作 | `proto/v2/gateway_ws.proto` 加帧臂 → pbws 本地处理器 → 客户端方法。 |
-| proto 演进纪律 | CI `buf breaking`（WIRE_JSON）把关；删除字段用 `reserved`；v2 业务消息永不改号、永不弃用。 |
-| 新增 settings 字段 | GUI settings normalize/storage、Rust settings save/load、Gateway redaction whitelist、WebUI settings copy 都要同步。 |
-| 新增 history 字段 | Rust summary model、proto `ConversationSummary`、GUI/WebUI sidebar render 都要同步。 |
-| 新增 chat event | Desktop event publisher、proto enum、Gateway 事件规范化与 `chat_event` payload、WebUI event reducer/transcript 都要同步。 |
-| 涉及 secret | 默认不进普通 sync，必须设计单向或显式更新通道。 |
+| 新增后端 command | 在 `src-tauri/src/tauri_commands/*.rs` 加 `#[tauri::command]` → `make update-routes` → 提交生成的 `routes_gen.rs`。**前端分流表不用改**（反向白名单） |
+| 新增壳专属 command | 加进 `commandRouting.ts::SHELL_ONLY_COMMANDS`，否则会被当成后端命令打到网络上 |
+| 新增事件 | 发布方 emit → 前端订阅。若发布方是壳，还要加进 `isShellEvent()` |
+| 新增 chat 事件 | 引擎 `emitEvent()` → 前端 `useBackendEventSubscription` 加分支。payload 必须带 `conversation_id`，否则前端路由不到会话 |
+| 改命令参数名 | 参数名**就是** JSON key，改名即破坏前端。`rename_all` 也一样 |
+| 涉及 secret | 密钥现在只在后端。前端不再持有 provider key，也就不需要脱敏快照那一套 |
+| 新增出网调用 | 过 `ssrf.rs` 的校验，别绕开 |

+# settings 契约分裂：现状归类与收敛路线（任务 #9）
+
+日期：2026-08-07。本文是任务 #9 的第一阶段产出：把两份 settings 的漂移逐块归类，
+说明哪些是真分叉（没有）、哪些是合法差异，并给出后续收敛的推荐路径。
+止血带门禁已上线：`make check-settings-drift`（CI 已接）。
+
+## 结论先行
+
+**两份 settings/index.ts 之间不存在同名函数的逻辑分叉。**
+前端版（2666 行）是 core 版（2183 行）的**严格超集**：core 的每一行都按原顺序
+出现在前端版里（除下述登记过的 core 独有行）。所谓"420 行漂移"实为：
+
+- 前端在共享逻辑之上追加了约 500 行**纯 UI 符号**；
+- core 额外持有 **providerIdentities**（CLI 身份，引擎独用，前端整个 repo 无引用）；
+- 若干 import 路径差异（`../i18n` vs `../../i18n`、`shared/` vs `system/`）。
+
+`mcpOps.ts`、`normalize.ts` 两侧逐字节相同。`storage.ts` 是**有意的两个实现**
+（core 走 HTTP callBackend 只取引擎所需分片；前端走 tauri invoke + localStorage
+UI 偏好 + gateway 同步），不是副本，不在收敛范围。
+
+`core/src/i18n/config.ts` 只是 7 行的 Locale shim（类型 + normalizeLocale），
+不是前端 4523 行翻译表的副本 —— "i18n 目录去留"问题消解：保留 shim 即可。
+
+## 漂移逐块归类
+
+### A. 前端独有（纯 UI，core 不需要）
+
+| 块 | 符号 | 归类 |
+|---|---|---|
+| Theme 交互 | `resolveEffectiveTheme` / `getNextTheme` / `subscribeToSystemThemePreference` / `THEME_OPTIONS` / `SYSTEM_THEME_MEDIA_QUERY` | window.matchMedia，DOM 独有 |
+| RightDock 状态机 | `getRightDockWriterId`（localStorage）、`updateRightDockProjectState`、tab 开关/tombstone/合并全套、`DEFAULT_RIGHT_DOCK_FILE_TREE_STATE`、`rightDockToolKindForTabId`、`RightDockTabKind` | 多客户端 UI 布局同步 |
+| settings 更新器 | `updateSystem/updateMcp/updateAgents/updateSsh/updateSkills/updateMemorySettings/updateCustomProviders/setSelectedModel/updateUpdateSettings/updateChatTranscriptWidth/updateRightDockWidth` 等 | React setState 风格包装,core 直接读不改写 |
+| 杂项 UI | `CLOSE_WINDOW_BEHAVIOR_OPTIONS`、`CODEX_REQUEST_FORMAT_LABELS`（文案）、`isValidSystemProxyHost`（表单校验）、`isThinkingAlwaysOnForModel`、`updateChatRuntimeControlsForProvider`（设置面板写路径） | 表单/展示层 |
+| SSH 项目关联 | `getSshProjectHostIds` / `updateSshProjectHostIds` / `removeSshHostFromProjectAssociations` | 设置页写路径 |
+
+### B. core 独有（引擎专用）
+
+- `providerIdentities: CliIdentitySettings`（customSettings 字段 + normalize 调用）。
+  消费方全在 core：engine.ts、cronPromptRunner、conversationTitle、memory organizer、
+  providerRuntimeConfig。前端 repo 零引用；backend 的 `settings_load_all` 也不返回
+  customSettings，所以 core 里它恒为 `normalizeCliIdentitySettings(undefined)` 的
+  默认值 —— 目前实际上是"默认值直通"，将来 CLI 身份持久化落地时才有真数据。
+
+### C. import 路径差异（同物异位）
+
+- `i18n/config`：core 是 7 行 shim，前端是完整翻译表；两者的 `Locale/DEFAULT_LOCALE/normalizeLocale` 语义一致。
+- `fontFamily`：core `shared/fontFamily.ts`（15 行纯 normalize），前端 `system/fontFamily.ts`（224 行，含 DOM 应用/本地字体枚举），前端超集。
+- `shared/id.ts`：前端版多 WebView 降级路径（crypto.randomUUID 缺失时的手搓 UUID），core 版直接调 randomUUID。语义兼容（core 跑 Node 22，randomUUID 恒存在）。
+- transcript 宽度常量：前端从 `transcript-width/transcriptWidthModel.ts` 导入，core 就地定义同值。数值一致性由门禁的 VALUE_GUARDS 守着。
+
+## 磁盘格式（Never break userspace 审计）
+
+持久化面完全没动、也不需要动：
+
+- SQLite（backend `settings_load_all` / `settings_save_*`）：providers/system/mcp/agents/ssh/remote/memory 七个分片。两侧读的是同一批端点、同一套 normalize。
+- localStorage `liveagent.ui-settings.v1`：skills/chatRuntimeControls/customSettings/updates/selectedModel/theme/locale/closeWindowBehavior，前端独有。
+- gateway 同步 payload（`sync.ts`，前端独有）：字段白名单机制，未受影响。
+
+## 收敛路线（后续任务，按风险从低到高）
+
+1. **【低】前端 index.ts 重排为 "镜像段 + UI 追加段"**：把前端文件重排成
+   「与 core 逐字一致的前缀 + 文件末尾的 UI-only 追加区」，门禁即可从
+   "有序子序列"升级为 wireEvents 式的"前缀逐字比对"，drift 检测从行级模糊
+   变成字节级精确。纯移动代码，无语义变化，但 diff 巨大，需要单独一轮评审。
+2. **【中】UI 符号拆出 `settings/ui.ts`**：前端把 A 类符号移入新文件，
+   index.ts 退化为 core 的纯镜像 + re-export。约 76 个 import 调用点不用改
+   （barrel re-export 兜住），但 500 行搬家 + 内部私有依赖
+   （`normalizeChatRuntimeReasoningForLevels` 等需要 core 侧导出或复制）要理顺。
+3. **【高】消副本**：前端直接 import core 源（跨 crate 相对路径 / workspace 包 /
+   构建期生成镜像三选一）。牵扯 vite、tauri、测试 loader 三套解析，且 core 的
+   `settings/index.ts` import 链会把 providers/models 一串模块拖进前端 bundle，
+   需要先量 bundle 影响。这是终态，但必须等 1、2 落地后单独立项。
+
+在 1-3 落地前，`check-settings-drift` 保证两侧不再悄悄分叉。
+
+## 本任务改动清单
+
+- 新增 `scripts/check-settings-drift.mjs`（门禁脚本，含 core 独有行白名单与
+  transcript 宽度常量值守卫）。
+- `Makefile` 新增 `check-settings-drift` 目标；`.github/workflows/ci.yml` 接入。
+- 本文档。
+- **未改任何 settings 运行代码** —— 归类阶段刻意零行为变化。

-# WebUI 架构
-
-## 定位
-
-WebUI 是 Gateway 承载的浏览器端操作台。它复用/复制了大量 GUI 交互形态，但不直接执行 Agent、本地工具或 Tauri 命令。所有需要本地权限的操作都通过 Gateway WebSocket/HTTP 转发到桌面端。
-
-## 主要模块
-
-| 模块 | 路径 | 职责 |
-|---|---|---|
-| App shell | `crates/agent-gateway/web/src/App.tsx` | 登录、socket 生命周期、settings/history/chat 状态、页面切换、composer/transcript。 |
-| Socket client | `web/src/lib/gatewaySocket.ts` | v2 WebSocket（Protobuf 帧）请求/响应、广播监听、连接超时、原生 Chat Runtime 唤醒、Chat command ACK 恢复与错误处理；proto 生成代码位于 `web/src/lib/proto/gen/`。 |
-| Conversation stream | `web/src/lib/chat/stream/conversationStreamClient.ts` | 按会话持久订阅注册表：维护 `after_seq`/`stream_epoch` 游标、重连自动重订阅、gap resync 与有界退避重试。 |
-| Gateway types | `web/src/lib/gatewayTypes.ts` | WebUI 侧协议类型。 |
-| Settings storage | `web/src/lib/webSettings.ts`、`web/src/lib/settings/*` | 浏览器本地设置缓存、脱敏 provider snapshot、settings sync payload。 |
-| History sync | `web/src/lib/historySync.ts`、`web/src/lib/historyParser.ts` | 历史列表/详情同步，大历史 worker 解析。 |
-| Transcript | `web/src/components/GatewayTranscript.tsx`、`web/src/pages/chat/*` | WebUI 对话渲染、checkpoint、tool trace、composer/header。 |
-| Shared UI copy | `web/src/components/*`、`web/src/pages/*`、`web/src/lib/*` 中的镜像实现 | 与 GUI 对齐的 Settings、Hub、chat sidebar、image preview 等实现。 |
-| Tauri shims | `web/src/shims/*` | 将 `@tauri-apps/api/*` 替换为 WebUI 可用的 Gateway/browser 实现。 |
-
-## 连接与认证
-
-| 阶段 | 行为 |
-|---|---|
-| token 读取 | WebUI 从浏览器存储读取 token，或通过 LoginPage 输入。 |
-| socket 创建 | `getGatewayWebSocketClient(token)` 建立 `/ws/v2` 连接（Protobuf 二进制帧，子协议 `liveagent.v2.pb`）；连接建立总超时为 10 秒，认证另有 15 秒超时，旧连接迟到的 close 不会误伤新连接。 |
-| 状态订阅 | 订阅 Gateway status，展示 Desktop Agent online/offline。 |
-| 请求响应 | 所有 request 带 id，Gateway 用同 id 返回 payload 或 error。 |
-| Chat 唤醒 | 用户消息先即时 optimistic echo，再串行发送 `chat.prepare`；Gateway 通过关联原生 Ping/Pong 真正唤醒桌面 Chat Runtime，并让紧随其后的 command 复用同一 Agent session 上 2 秒内的新鲜探测，避免正常路径重复一个原生 RTT。准备请求最多等待 2.5 秒，旧 Gateway 不支持该方法时回退到 `status.get`，最终仍由 `chat.command` 作为兜底唤醒信号。 |
-| Chat 流 | 提交/编辑/取消走 WebSocket `chat.command`；ACK 最多等待 4 秒，连接中断或 ACK 丢失时只重试一次，并复用完全相同的 payload 与 `client_request_id`。流式输出走按会话持久订阅 `chat.subscribe`（`chat.event` 推送，seq 续传）。 |
-| 断线恢复 | WebSocket client 处理普通同步重连；Chat 订阅在 history snapshot hydrate 后重发 `chat.subscribe`，按同 conversation 单调递增的 `after_seq`（配合 `stream_epoch`）跨 run 补齐内存窗口内的缺失事件；单次订阅 5 秒超时，失败后以 250ms、500ms、1s、2s、5s 上限加 jitter 自恢复。观察正在运行的远程会话时优先使用 `history.list.running_conversations[].first_seq - 1` 作为当前 run 的订阅起点。 |
-
-## WebUI 本地状态
-
-| 状态 | 来源 | 用途 |
-|---|---|---|
-| `token` | 用户输入/localStorage | WebSocket 和 HTTP API 认证。 |
-| `settings` | Gateway `settings.get`、`settings.event`、local redacted cache | 渲染 Settings、Chat mode、model list、MCP/Skills/Memory 等。 |
-| `historyItems` | Gateway `history.list`、`history.event` | 侧边栏、pin/share/delete/rename。 |
-| `visible transcript` | `history.get`、live chat events、本地 draft | 当前会话内容。 |
-| `live stream cache` | Chat Command 返回、`chat.subscribe` replay 与 `chat.event` 推送 | 保持运行中会话流式可见。 |
-| `draft conversation` | WebUI 本地临时 id | 新对话提交后迁移到桌面端返回的真实 conversationId。 |
-| upload cache | HTTP upload response | 将导入后的 `ChatUploadedFile` 附到下一次 Chat Command。 |
-
-## 与 GUI 的共享和分离
-
-| 维度 | 说明 |
-|---|---|
-| 视觉/交互 | Settings、Skills Hub、MCP Hub、Chat sidebar、AssistantBubble 等与 GUI 保持 parity。 |
-| 源码组织 | WebUI 保留自己的复制/镜像文件，不直接从 `agent-gui` import 大量源码。右侧边栏（project-tools）与 `lib/workspace-activity` 的镜像文件必须逐字节一致：清单在 `scripts/mirror-manifest.json`，CI 以 `node scripts/check-mirror.mjs` 强制校验；平台差异只允许出现在两端各自的适配文件（ChatPage/GatewayApp、workspace-activity client、SshTunnelPanel）。 |
-| Tauri API | WebUI 通过 Vite alias 指向 shims，避免真实 Tauri 依赖进入浏览器运行时。 |
-| 数据通道 | GUI 走 Tauri invoke；WebUI 走 Gateway WebSocket/HTTP。 |
-| 执行权限 | GUI 可以触发本地工具；WebUI 只能请求桌面端代执行。 |
-
-## WebUI 支持的主要 Gateway 方法
-
-| 方法族 | 示例 |
-|---|---|
-| Auth/status | `status.get`、socket auth/unauthorized handling |
-| Chat | WS `chat.prepare`、`chat.command`（`chat.submit`/`chat.edit_resend`/`chat.cancel`）、`chat.subscribe`/`chat.unsubscribe`、`chat.activities`；事件经 `chat.event`/`chat.command_update` 推送 |
-| History | `history.list`、`history.get`、`history.rename`、`history.pin`、`history.share.get`、`history.share.set`、`history.delete` |
-| Settings | `settings.get`、`settings.update` |
-| Providers | `providers.list`、provider model scan related request |
-| Skills | `skills.list`、`skills.manage`、`skills.read-metadata`、`skills.read-text` |
-| MCP | MCP settings 通过 settings 更新；运行期工具由桌面端执行。 |
-| Cron | `cron.manage` |
-| Memory | `memory.manage` |
-| Files | upload HTTP `/api/files/import`，mentions/fs roots/list dirs 走 Gateway request。 |
-
-## Provider Secret 处理
-
-| 场景 | 处理 |
-|---|---|
-| GUI -> Gateway settings sync | provider API key 被 redaction，只同步 `apiKeyConfigured` 等 presence 信息。 |
-| Gateway -> WebUI | WebUI 只能看到脱敏快照。 |
-| WebUI 保存已有 provider | 未输入新 key 时不把空/脱敏值覆盖回 GUI 真实 key。 |
-| WebUI 输入新 key | 通过 `providerApiKeyUpdates` 单向发回 GUI 更新。 |
-| WebUI localStorage | 保存 redacted provider settings，避免浏览器长期保存真实 secret。 |
-
-## WebUI 的重要限制
-
-| 限制 | 影响 |
-|---|---|
-| 不直接执行工具 | Shell、FS、MCP、Memory mutation、Cron prompt 都必须回到桌面端。 |
-| 依赖 Gateway 在线 | Gateway 或 Desktop offline 时，Chat/Settings/History 能力受限。 |
-| 复制维护成本 | 列入 `scripts/mirror-manifest.json` 的文件由 CI 逐字节校验，改动必须双端同 PR 落地；未列入清单的镜像组件仍需双端一起检查。 |
-| 浏览器存储不是权威 | Settings 和 history 的真实来源仍是桌面端 SQLite 与 Gateway sync。 |
-| Gateway relay 不是持久历史 | `chat.subscribe` 的 seq replay 来自 Gateway 进程内的有界事件窗口；Gateway 重启或窗口 reset 时，WebUI 以桌面历史 snapshot 重新 hydrate。 |

+只有两种，区别在于**后端跑在哪台机器上**：
 
-| 入口 | Workflow | 动作 |
-|---|---|---|
-| PR / `main` push | `.github/workflows/ci.yml` | 跑 Gateway、WebUI、GUI、Tauri Rust 测试和 proto 一致性检查。 |
-| `v*` tag / 手动指定 tag | `.github/workflows/gateway-docker.yml` | 构建并推送 `vX.Y.Z` 与 `latest` Gateway 镜像。 |
-| `v*` tag / 手动指定 tag | `.github/workflows/desktop-release.yml` | 并行构建 macOS Intel、macOS Apple Silicon、Windows x64 和 Linux x64 桌面包，并上传到 GitHub Release。 |
+| 形态 | 后端 | 前端 | 适用 |
+|---|---|---|---|
+| 桌面端自带 | Tauri 壳在自己进程里起 `backend`，监听 `127.0.0.1:<随机端口>` | 壳内 WebView | 单机使用，装完即用 |
+| 独立后端 | Docker 跑 `backend`，监听 `0.0.0.0:8443` | 浏览器打开同一台机器提供的页面并填地址+密码 | 后端放服务器/家里的机器，从别处访问 |
+
+两者**不能同机并跑**——共用同一个 `~/.liveagent` 数据目录。
+
+> **NAT 穿透不再是应用的事。** 后端在家、人在公司仍然要打洞，但这现在是**网络
+> 问题**：用 tailscale / frp / cloudflared 任选其一。应用里不再有会合注册代码
+> （旧 Go gateway 那约 1,100 行随阶段 6 一起删除）。这不是功能退化，是把网络问题
+> 还给网络工具——它们做得比我们好，而且用户本来就在用。
 
-## Gateway 镜像
+## 后端镜像
 
-根目录 `Dockerfile` 是 Gateway 的生产镜像：
+根目录 `Dockerfile`，三阶段：
 
 | 阶段 | 内容 |
 |---|---|
-| `webui` | 用 Node 22 和 pnpm 构建 `crates/agent-gateway/web/dist`。 |
-| `gateway-builder` | 用 Go 编译 `cmd/gateway`，WebUI 静态资源通过 `go:embed` 打进二进制。 |
-| `runtime` | Debian slim + CA certificates + `liveagent-gateway`，非 root 用户运行。 |
+| `engine-builder` | Node 22 + pnpm，`tsc --noEmit` + esbuild 把 `core` 打成单文件 `dist/index.js` |
+| `backend-builder` | Rust，`cargo build -p backend --release` |
+| `runtime` | `node:22.19.0-bookworm-slim`，非 root（uid 10001），Rust 二进制 + 引擎 bundle |
 
-运行时变量：
+```
+ENV LIVEAGENT_DATA_DIR=/var/lib/liveagent LIVEAGENT_ENGINE_BUNDLE=/opt/liveagent/engine HOME=/var/lib/liveagent
+VOLUME ["/var/lib/liveagent"]
+EXPOSE 8443
+ENTRYPOINT ["/usr/local/bin/backend"]
+```
 
-| 变量 | 必填 | 说明 |
-|---|---|---|
-| `LIVEAGENT_GATEWAY_TOKEN` | 是 | WebUI、HTTP API、桌面端 v2 WebSocket 的共享访问 token。 |
-| `PORT` | Railway 自动提供 | HTTP/WebUI/桌面端 WebSocket 监听端口，未提供时 Dockerfile 默认 `8080`。 |
-| `LIVEAGENT_GATEWAY_CHAT_PREPARE_TIMEOUT` | 否 | `chat.prepare` 与 command accepted 前关联原生 Ping/Pong 的最大等待时间，默认 `2s`。 |
-| `LIVEAGENT_GATEWAY_CHAT_DELIVERY_TIMEOUT` | 否 | accepted 后把 `ChatCommandRequest` 投递到当前桌面 Agent stream 的最大等待时间，默认 `5s`。 |
-| `LIVEAGENT_GATEWAY_CHAT_START_TIMEOUT` | 否 | Chat command 进入桌面运行态的第一段 watchdog，默认 `5s`。 |
-| `LIVEAGENT_GATEWAY_CHAT_RENDER_START_TIMEOUT` | 否 | 第一段 watchdog 后继续等待桌面 run settled 的附加窗口，默认 `10s`。 |
+运行时基底是 `node:*-slim` 而不是 `debian-slim`：Node runtime 要随产物分发
+（决策 3），自带比手装干净。**代价是镜像比旧的 Go 版本大**——这是决策 3 的已知
+成本，记下来而不是假装没有。
 
-本地 smoke run 示例：
+本地构建与冒烟：
 
 ```bash
-make gateway-docker-smoke
+make backend-docker-build     # docker build -t liveagent-backend:local .
+make backend-docker-run       # -p 8443:8443
+make backend-docker-smoke     # 起容器 + 轮询 /healthz，60s 上限
 ```
 
-CI 中的 `Gateway Docker Smoke` job 会执行同等检查：构建镜像、启动容器、访问 `/healthz`。
+冒烟给 60s 而不是 30s：Node 引擎的就绪探测本身最多等 30s。
 
-## 用户自部署 Gateway
+## 启动参数
 
-LiveAgent 不提供托管 Gateway 服务。需要公网 Remote Gateway 的用户可以用自己的 Railway 账号部署本仓库，或在其他 Docker 平台部署 `ghcr.io/<owner>/liveagent-gateway:vX.Y.Z` / `latest` 镜像。
+`backend` 每个命令行参数都有环境变量兜底，**argv 优先**（手写解析，
+不引 clap——四个参数不值一整棵依赖树）：
 
-Railway 自部署路径：
+| 参数 | 环境变量 | 默认 | 说明 |
+|---|---|---|---|
+| `--port <PORT>` | `PORT` | `8443` | 监听端口，绑 `0.0.0.0`。Railway 一类平台注入的 `PORT` 直接生效 |
+| `--password <PW>` | `LIVEAGENT_BACKEND_PASSWORD` | `pleasechangethepassword` | Bearer token。不给就用这个众所周知的默认值并在 stderr 警告——对外部署**必须**显式设置 |
+| `--engine-bundle <DIR>` | `LIVEAGENT_ENGINE_BUNDLE` | 无 | Node 引擎 bundle 目录（内含 `index.js`）。不给则以**纯 API 模式**运行——命令全部可用，但没有 chat |
+| `--data-dir <DIR>` | `LIVEAGENT_DATA_DIR` | `~/.liveagent` | 数据目录。官方镜像预设为 `/var/lib/liveagent` |
 
-1. 在 Railway 新建项目，选择 GitHub Repository。
-2. 选择 `Stack-Cairn/LiveAgent` 或用户自己的 fork。
-3. 分支选择包含根目录 `Dockerfile` 和 `railway.json` 的分支。
-4. 在 service variables 中设置 `LIVEAGENT_GATEWAY_TOKEN=<long-random-token>`。
-5. 部署成功后生成 Public Domain，并访问 `/healthz` 验证健康检查。
+## TLS
 
-推荐生产部署模型：
+后端只监听明文 HTTP，不内建 TLS。对外部署时由外层终结加密，二选一：
 
-| 流量 | Railway 能力 | Remote 配置 |
-|---|---|---|
-| WebUI / HTTP / 桌面端 WebSocket（`/ws/v2*`） | Public Networking HTTPS 域名 | 桌面端设置 `Gateway URL=https://<service>.up.railway.app`，网关端口填 `443`。 |
+| 方式 | 配置 |
+|---|---|
+| 反向代理 | nginx / Caddy / 平台（Railway 等）终结 TLS |
+| 隧道 | tailscale / cloudflared 自带加密 |
 
-全部实时链路统一走同一 HTTPS 域名与端口。
+## 数据持久化
 
-Gateway 运行时变量由用户在自己的平台配置：
+后端把全部状态写在**数据目录**下（`backend/src/storage.rs`）。解析顺序：
+`--data-dir` → `LIVEAGENT_DATA_DIR` → 运行用户的 `~/.liveagent`（路径是写死的
+字符串，不随包名漂移——桌面壳不传参数，永远落在 `~/.liveagent`）：
 
-| 变量 | 说明 |
-|---|---|
-| `LIVEAGENT_GATEWAY_TOKEN` | WebUI、管理 API 与 Agent 链路使用的网关 Token；Agent 也可使用独立凭证。 |
-| `LIVEAGENT_GATEWAY_AGENT_DB` | Agent 凭证 SQLite 路径；缺省自动创建，无需手动设置。 |
-| `LIVEAGENT_GATEWAY_DATA_DIR` | 自动数据库的父目录；官方容器默认 `/var/lib/liveagent`，直接运行二进制时默认使用用户配置目录。 |
-| `LIVEAGENT_GATEWAY_CHAT_PREPARE_TIMEOUT` | 默认 `2s`；通常无需调大，超时应暴露半开连接并让客户端快速恢复。 |
-| `LIVEAGENT_GATEWAY_CHAT_DELIVERY_TIMEOUT` | 默认 `5s`；控制 accepted 后投递桌面 stream 的上限。 |
-| `LIVEAGENT_GATEWAY_CHAT_START_TIMEOUT` | 默认 `5s`；控制远程 command 启动 watchdog 的第一阶段。 |
-| `LIVEAGENT_GATEWAY_CHAT_RENDER_START_TIMEOUT` | 默认 `10s`；控制启动 watchdog 的附加阶段。 |
+```
+<数据目录>/
+  config.sqlite               设置
+  chat-history.sqlite3        会话历史 + FTS
+  memory/**/*.md              记忆事实源
+  memory/memory-index.sqlite3 记忆索引
+  skills/                     Skills root
+  uploads/<batch>/            上传暂存
+```
 
-Gateway 的 conversation stream replay 与 `client_request_id` 去重当前都是进程内有界状态，本身不需要持久卷。事件窗口默认保留最近 10 分钟、最多 4096 条或约 8 MiB；command 去重记录保留 24 小时，但 Gateway 进程重启后不会保留。Gateway 默认自动创建每 Agent 凭证数据库（SQLite）；可用 `-agent-db` 指定路径。生产部署需要把数据库目录挂载到持久卷；官方 Docker 命令使用 `-v liveagent-gateway-data:/var/lib/liveagent`，否则重建容器会丢失已签发的凭证（见 [multi-agent.md](multi-agent.md)）。
+**密钥也在这里。** provider API key 存在后端的设置库里，前端不再持有它们。所以
+「密钥只在本地」这句话现在应该说成**「密钥只在后端，后端由你自己部署」**——如果
+你把后端放在别人的服务器上，密钥就在别人的服务器上。
 
-升级时旧启动脚本中的 `-grpc-addr` 和 `-command-queue-timeout` 会在新版参数解析前被移除，不会出现在 `--help`，也不会恢复已删除的 v1/gRPC 或离线命令队列。`-grpc-max-message-bytes` 与 `LIVEAGENT_GATEWAY_GRPC_MAX_MESSAGE_BYTES` 会映射到当前 WebSocket protobuf 消息上限；新名称 `-max-message-bytes` 和 `LIVEAGENT_GATEWAY_MAX_MESSAGE_BYTES` 优先。其他未知参数仍会报错，避免隐藏配置拼写错误。
+> **官方镜像的数据卷**：镜像预设 `LIVEAGENT_DATA_DIR=/var/lib/liveagent` 并声明
+> `VOLUME ["/var/lib/liveagent"]`（目录已建好、归 uid 10001）。持久化只需挂卷：
+> `docker run -v liveagent-data:/var/lib/liveagent ...`。不挂卷则数据随容器删除而丢失。
 
-## GitHub Secrets
+## 客户端接入
 
-macOS signed/notarized release 需要这些 secrets：
+### 浏览器
 
-| Secret | 说明 |
-|---|---|
-| `APPLE_CERTIFICATE_P12_BASE64` | Developer ID Application `.p12` 的 base64。 |
-| `APPLE_CERTIFICATE_PASSWORD` | 导出 `.p12` 时设置的密码。 |
-| `APPLE_SIGNING_IDENTITY` | `Developer ID Application: wenlin fei (UU94JSVAA9)`。 |
-| `APPLE_ID` | Apple Developer 账号邮箱。 |
-| `APPLE_TEAM_ID` | `UU94JSVAA9`。 |
-| `APPLE_APP_SPECIFIC_PASSWORD` | Apple app-specific password。 |
-| `TAURI_SIGNING_PRIVATE_KEY` | Tauri updater 私钥，用于生成 release 更新包签名。 |
-| `TAURI_SIGNING_PRIVATE_KEY_PASSWORD` | Tauri updater 私钥密码；无密码时可为空。 |
-| `TAURI_UPDATER_PUBLIC_KEY` | Tauri updater 公钥，会编译进桌面端用于校验更新包。 |
-
-脚本化写入 GitHub 配置：
+打开前端页面后，登录页填三项：主机、端口、密码。也可以直接发链接，跳过登录页：
 
-```bash
-BOOTSTRAP_APPLE_SECRETS=1 \
-APPLE_CERTIFICATE_PASSWORD=<p12-export-password> \
-  scripts/release/bootstrap-github-secrets.sh
+```
+https://your-box:8443/?backendHost=your-box&backendPort=8443&token=<password>&secure=true
 ```
 
-如果 `CERT_DIR/developer_id_application.p12` 不存在，脚本会从本机 Keychain 中的 `Developer ID Application: wenlin fei (UU94JSVAA9)` 自动导出，并生成 `.p12` 密码写入 GitHub Secret。`CERT_DIR` 默认优先使用 `~/Personal/cert`，不存在时使用 `~/Downloads/cert`。已有 `.p12` 时需要传入 `APPLE_CERTIFICATE_PASSWORD=<p12-password>`。
+URL 参数会被持久化到 localStorage，下次打开不用重填。`secure` 缺省跟随页面协议。
 
-如果自动导出失败，先确认本机能看到可签名 identity：
+一个后端支持**多个前端同时连**（决策 9）。前端不在场不阻塞后端主流程（决策 10）：
+对话照跑，工具审批该超时超时、有推荐项自动选。
 
-```bash
-security find-identity -v -p codesigning "$HOME/Library/Keychains/login.keychain-db"
-```
+### 桌面端
+
+桌面端连的是**它自己进程里那个后端**：`get_backend_endpoint` 返回的 host 恒为
+`127.0.0.1`，端口和密码由壳注入，用户永远不输密码、也看不到登录页。
 
-Keychain 中必须是带私钥的 `Developer ID Application` identity。若 macOS 拒绝私钥导出，可以在 Keychain Access 中手动导出 `.p12` 到 `P12_PATH`，再用同一个 `APPLE_CERTIFICATE_PASSWORD` 重新运行脚本。
+> ⚠️ **桌面壳目前无法连接远程后端。** `commands/app/backend.rs` 只会返回内嵌后端
+> 的端点，没有填写远程地址的入口。阶段 6 验收里「Docker 跑 headless 后端，
+> 笔记本上的桌面端连过去」这一条**当前实现不支持**，远程访问只有浏览器一条路。
 
-脚本默认读取：
+## 从旧 Gateway 迁移
 
-| 文件 | 用途 |
+| 项 | 处置 |
 |---|---|
-| `CERT_DIR/developer_id_application.p12` | CI 导入的签名 identity。 |
-| `CERT_DIR/app key.md` | Apple app-specific password。 |
+| 旧镜像 `ghcr.io/<owner>/liveagent-gateway` | **历史 tag 全部保留、仍可拉取**（决策 15）。只是不再发布新 tag |
+| 新镜像 | `ghcr.io/<owner>/liveagent-backend:vX.Y.Z` / `:latest` |
+| 旧桌面端 | 仍可连旧 gateway 镜像。这是大版本切换，不是原地升级 |
+| `LIVEAGENT_GATEWAY_*` 环境变量 | 全部作废。新后端认 `PORT`、`LIVEAGENT_BACKEND_PASSWORD`、`LIVEAGENT_ENGINE_BUNDLE`、`LIVEAGENT_DATA_DIR`（argv 优先） |
+| 每 Agent 凭证、`agent_id`、多 Agent 目录 | 概念消失。一个前端只连一个后端（决策 12） |
+| 浏览器里的旧 token | 前端检测到 `liveagent.gateway.token` 会在登录页给迁移提示 |
 
-## 桌面产物
+## CI
 
-`desktop-release.yml` 产物：
+`.github/workflows/ci.yml`：
 
-| 平台 | Runner | 产物 |
+| Job | 内容 |
+|---|---|
+| Backend Rust | `make check-routes`（生成物漂移）、**`cargo tree -p backend \| grep tauri` 命中即失败**、`cargo test` + `clippy -D warnings` |
+| Backend Docker Smoke | 构建镜像、起容器、轮询 `/healthz` |
+| GUI | 前端测试 |
+| Tauri Rust Check | `src-tauri` 单独跑（它要 GTK/WebKit，不能塞进后端 job） |
+| Diff Hygiene | 空白字符检查 |

-# 多 Agent 与凭证管理
-
-网关支持多台桌面 Agent 同时在线（个人多设备到上百台规模），浏览器可分别
-控制任意一台。本文是部署与凭证运维手册；协议细节见
-[protocols.md](../architecture/protocols.md)。
-
-## 部署清单
-
-1. 每个桌面端首次初始化设置时都会生成全局唯一且稳定的 `agent-UUIDv4`，可在
-   “设置 → Remote → Agent ID”中查看和复制。该标识由客户端管理，用户不能修改；
-   不同客户端独立生成，不依赖 hostname。
-2. 网关默认自动创建每 Agent 凭证存储。凭证存于内嵌 SQLite 数据库
-   （纯 Go 驱动，无需额外安装任何东西）；需要固定位置时可指定数据库路径：
-
-   ```bash
-   liveagent-gateway \
-     -token "<网关 Token，浏览器与 REST 使用>" \
-     -agent-db /var/lib/liveagent/agents.db
-   ```
-
-   等价环境变量：`LIVEAGENT_GATEWAY_AGENT_DB`。**容器部署必须在
-   `/var/lib/liveagent` 挂载持久卷**，否则重启丢凭证。
-
-   不指定 `-agent-db` 时，数据库默认创建在
-   `LIVEAGENT_GATEWAY_DATA_DIR/gateway.db`，或用户配置目录下的
-   `liveagent/gateway.db`。Agent 链路同时接受网关 Token 和按 `agent_id` 签发的
-   独立凭证；无论使用哪种凭证，Agent 都必须携带稳定的 `agent_id`。
-
-3. 桌面端可直接将网关 Token 填入“访问令牌”并连接。若改用独立凭证，先复制
-   桌面端自动生成的 Agent ID，在 WebUI“设置 → 多客户端管理”中粘贴该 ID，
-   可选填写客户端名称并签发，再把响应中的 `agt_...` 填回该桌面端的“访问令牌”。
-4. WebUI 首次连接会从 `agent_list` 自动选择一个在线 Agent；多 Agent 场景可在
-   顶栏选择器切换，后续所有目标型请求都会携带明确 `agent_id`。
-
-## 并发连接上限
-
-三条 v2 链路的并发连接上限可配置（超限的连接在升级前收到 503）：
-
-| flag | 环境变量 | 默认 |
-|---|---|---|
-| `-max-agent-connections` | `LIVEAGENT_GATEWAY_MAX_AGENT_CONNECTIONS` | 256 |
-| `-max-browser-connections` | `LIVEAGENT_GATEWAY_MAX_BROWSER_CONNECTIONS` | 128 |
-| `-max-terminal-connections` | `LIVEAGENT_GATEWAY_MAX_TERMINAL_CONNECTIONS` | 512 |
-
-## 凭证运维
-
-有两种方式管理 Agent 凭证：**管理界面**（推荐）或 **curl**。
-
-### 管理界面
-

-|---|---|---|---|
-| 网关 Token | ✅ | ✅ | ✅ |
-| Agent 凭证（agt_*） | ❌ | 仅限签发时绑定的 agent_id ✅ | ❌ |
-
-- 单个 Agent 凭证泄露的最大损害 = 冒充/顶替**该一台** Agent；无法控制其他
-  Agent、无法冒充浏览器（控制端）、无法调用管理 API。
-- 未知 agent_id 与错误凭证统一报 "unauthorized"（常量时间比较，防枚举）。
-- 跨 Agent 隔离由网关按已认证会话身份强制：事件打标、快照分仓、隧道帧
-  stream_id 归属校验，Agent 无法伪造他人身份的数据。
